人民币的换算是小学1年级数学的重点知识,不光考试会重点考察,连生活中购物消费都会使用到。不少家长觉得,现在出门一般都是移动设备支付,不需要掌握钱币的换算。其实,这样的想法是错误的,因为这种类型的计算题可以培养孩子的思维能力,为高年级学习数学大打下基础。
Many parents feel that going out is usually a mobile device to pay for the conversion without having to hold the money. In fact, the idea is wrong, because this type of calculation builds a child's mental skills and lays the foundation for learning mathematics in the higher grades.
然而,不少同学熟悉了换算公式,但是在做题的时候还是容易出错,这其实也从侧面反映出了小朋友们对公式的掌握还不够熟悉、所以,今天老师精心给同学们整理了一篇人民币专题换算的练习题,包含了换算、计算、应用题等题型,家长朋友们可以给孩子打印下来做一做,巩固一下课堂知识。相信对孩子是有所帮助的。
However, many students are familiar with the conversion formula, but it is easy to make mistakes when working on the subject, which also reflects the fact that children are not familiar enough with the formula, so today the teachers have carefully organized for the students an exercise on the conversion of the renminbi theme, which includes conversions, calculations, applications, etc., so that parents can print it for their children and consolidate their knowledge of the classroom.

一个比特币值多少人民币,比特币最高价格时值多少钱
How much is a bitcoin and how much is a bitcoin when it's the highest price?
相信很多人都听说过比特币,这是一种网络虚拟货币,曾经比特币是很多人一夜暴富的梦想,尽管我国的监管机关多次提示比特币的风险,但是还是有很多人关注比特币,对于投资者来说比特币的价格是大家关注的重点,那么一个比特币值多少人民币?
It is believed that many have heard of Bitcoin, a virtual online currency that used to be the dream of many people who were rich overnight. Despite the fact that our regulatory authorities have repeatedly raised the risks of Bitcoin, a lot of people are concerned about bitcoin, and the price of bitcoin is the focus of attention for investors, so how much is a bitcoin worth?
比特币的概念是在2009年的时候,由一个名叫中本聪的人提出的,比特币是一种虚拟的数字货币,比特币和其它数字货币的最大不同就是比特币的数量是恒定的,比特币的总量被限制在2100万个。
The bitcoin concept was introduced in 2009 by a man named Bentley, a virtual digital currency, and the biggest difference between bitcoin and other digital currencies is that the number of bitcoins is constant and the amount of bitcoins is limited to 21 million.
比特币的价格是会随着时间、交易场所的不同而发生波动的,比特币属于一种高风险投资,其价格跌涨也是没有限制的,可能一夜之间暴富,也可能一夜之间亏的血本无归,关于比特币值多少人民币的问题,大家可以通过各大交易平台来看出比特币实时价格,比特币的价格每时每刻都在波动,4月16日,BCEX公布的最新比特币价格为34471.11元人民币,Bibox公布的价格为33878.19人民币。
The price of Bitcoin fluctuates over time and over time, depending on the place where the transaction takes place. Bitcoin is a high-risk investment, and its price falls and rises are unlimited, it may be rich overnight or it may lose blood overnight. With regard to the value of Bitcoin, real-time prices of Bitcoin can be seen through the main trading platforms, and the price of Bitcoin fluctuates from time to time. On 16 April, BCEX announced its latest price in bitcoin at RMB 34471.11 and Bibox at RMB 33878.19.
比特币从诞生到至今,其价格也是经历了多次跌涨,2009年比特币诞生初期,一美元可以买到1300枚比特币,在2010年的时候,比特币的价格在0.003美元左右一枚,直到2013年11月,比特币的价格经历了首次保障,当时一枚比特币的价格在8000元人民币左右,2017年比特币再次创造了奇迹,其价格在2017年12月的时候创造了历史最高价,一枚比特币的最高价值将近20000美元,换算成人民币,一枚比特币的价格将近13万人民币,也正是比特币的此次疯涨让无数人关注到了数字货币,在经历暴涨后,比特币的价格迅速暴跌了70%,可见比特币的投资风险是非常大的,大家入市需谨慎。
The price of Bitcoin, which had also experienced a number of price hikes from its birth to the present, was able to buy 1,300 bitcoins in the early days of the birth of Bitcoin in 2009, and in 2010, the price of bitcoin was about US$003. The price of bitcoin was guaranteed for the first time until November 2013, when the price of a bitcoin was around US$ 8,000, and in 2017 it was once again a miracle. The price of a bitcoin was the highest in history in December 2017, the value of a bitcoin was nearly US$ 20,000, converted into a renminbi, and the price of a bitcoin was nearly 130,000 yuan, which was the height of bitcoin, which drew the attention of countless people. After the surge, the price of bitcoin fell rapidly by 70 per cent.
导语:如今人们的经济状况都比以前好了很多,那么旅游就成为了生活中的一部分。在闲暇的时候跟自己的家人或者三五个好友一起到一个陌生的地方玩乐,不仅可以感受不同的美景风光,还能释放自己内心的压抑。除了国内游以外,很多人也会选择走出国门去看一看,不过我们都知道,每个国家的货币是不一样的,在选择去一个国家之前,要提前换好货币,做好充分的准备才能出发。
Guide: People now have a much better economic situation, so tourism becomes part of life. Having fun with their families or three or five friends at leisure in a strange place, they can not only feel different landscapes, but also release their own internal repression. Many people, in addition to travelling within the country, also choose to look outside the country, but we all know that each country's currency is different, and before choosing to go to a country, change it well enough to get ready to go.
说到这,我们今天就来讲一讲韩国,这可是很多年轻女孩都向往的一个国家。也许是韩剧看多了,也许是觉得这个国家的文化很吸引人,总之大家都很向往这个地方。那么有的网友就好奇了,要是哪个五千块钱去哪里,够玩几天呢?
Speaking of which, we're talking about South Korea today, it's a country where many young girls are looking for. It's probably a lot of Korean drama. It's a country where people think it's attractive, and everyone wants this place anyway. So some of them wonder, what kind of $5,000 is there to go for a few days?
答案让你意想不到。首先我们都知道,韩国的货币是很不值钱的,随便一个衣服啊鞋子啊都是好几万,实际上换算成人民币也值不了多少钱。那么五千块的话能换成八十多万的韩元。这个数字是不是听起来很庞大?但这跟他们的实际消费也是成比例的。
The answer surprises you. First of all, we all know that South Korea's currency is worthless, that there are tens of thousands of clothes and shoes, and that it is not worth much to convert into a renminbi. Then 5,000 won would be worth more than 800,000 won.
要是住一般酒店的话,每天大概是八万左右,吃饭就选择一些特色的小吃,每顿几十元,偶尔选择一顿大餐,一天差不多也就是几百块钱就能搞定。然后就是坐车,不要选择的士,价格是不便宜的,而且还有可能被坑。尽量选择公交车,只要规划好路线就可以。那么总共算下来的话五千块够玩十几天是没问题的。还真是挺划算的呢,怪不得大家都想去这个国家玩!
If you're staying in a hotel, it's about 80,000 a day, and you're going to eat something special, and you're going to have a few dozen dollars a day, and you're going to have a few hundred dollars a day. Then you're going to take a car, you don't choose a taxi, it's not cheap, and you're going to fall into a hole. You can choose a bus as long as you want.
小编觉得,说说自己都想去了,不过建议大家去之前一定要合理规划自己的行程,包括每天的消费等等,这样才能玩的更加顺利,不知你们对此怎么看呢?
The editor-in-chief thought that he wanted to go, but suggested that everyone should plan their travels properly, including daily consumption and so on, in order to have a better time. What do you think about that?

点评:本题是考查面积单位的意义、长度单位的意义,属于基础知识.注意,只有同属性的单位才能比较大小.
Review: The topic is what size units are, what length units are, what basic knowledge is. Attention, only units of the same identity can be compared to size.
五.长度的单位换算
V. Conversion by unit of length
1千米=1000米,
1 km = 1000 m,
1米=10分米=100厘米=1000毫米;
1 m = 10 m = 100 cm = 1000 mm;
1分米=10厘米=100毫米;
1 metre = 10 cm = 100 mm;
1厘米=10毫米.
1 cm = 10 mm.
单位之间的换算,大单位换算成小单位要乘它们之间的进率;小单位换算成大单位要除以它们之间的进率.
For conversion between units, large units are to be converted by multiplying the rate of progress between them; small units are to be converted by dividing the rate of progress between them.

Analysis: Depending on the subject, it is sufficient to convert 3.6 kilometers into rice units and then to answer them.
解:3.6×1000=3600;
Solver: 3.6 x 1000 = 3600;
所以,3.6千米=3600米;
So, 3.6 km = 3600 m;
故选:B.
Choosing: B.
点评:单位之间的换算,大单位换算成小单位要乘它们之间的进率;小单位换算成大单位要除以它们之间的进率.
Review: conversion between units, the large units are to be multiplied by the rate of progress between them; the small units are to be divided by the rate of progress between them.
例2:用“米”作单位计算,“8米6厘米十5米60厘米”的正确算式是( )
Example 2: Using "m" as a unit, the correct formula for "8 m6 x 105 m60 cm" is ()
A、8.6+5.6 B、8.06+5.06 C、8.06+5.6
分析:此题应先把复名数换算成单名数,再进行计算:
Analysis: This question should be converted to a single name before calculation:
(1)把8米6厘米换算成米数,先把6厘米换算成米数,用6除以进率100,得数再加上8即可;
(1) Conversion of 8 m6 centimetres into rice and 6 centimetres into rice, divided by a factor of 100 plus 8 centimetres;
(2)把5米60厘米换算成米数,先把60厘米换算成米数,用60除以进率100,得数再加上5即可,据此即可做出正确选择.
(2) Conversion of 5 m60 centimetres to rice, first conversion of 60 centimetres to rice, with a rate of 60 divided by 100, plus 5 so that the right choice can be made.
解:因为8米6厘米=8.06米,
Solver: Because 8 m6 = 8.06 m,
5米60厘米=5.6米,
5 m 60 cm = 5.6 m,
所以8米6厘米十5米60厘米=8.06+5.6(米);
So 8 m6 x 105 m60 cm = 8.06 + 5.6 m;
点评:此题考查名数的换算,把高级单位的名数换算成低级单位的名数,就乘单位间的进率,反之,则除以进率.
Review: The conversion of the number of names on this question by converting the number of names of the senior units into the number of names of the lower units, by multiplying the rate of progress between units and, conversely, by dividing it by the rate of progress.
很多家长朋友都会困惑在家辅导孩子人民币换算,今天小编和大家一起分享一下。
Many parents and friends are confused about tutoring their children at home in the conversion of the renminbi, and the editor-in-chief is sharing it with you today.
首先大家一定要清楚一点再辅导孩子:您面对的是年龄不足十岁的小宝贝,他们的生活经历不是很丰富,理解力上远远不及我们成年人,对于人民币的接触实在是太少了!
First of all, let's be clear: you're dealing with little babies under the age of ten, who have not had a very rich life experience, who have far less understanding than our adults, and who have little contact with the renminbi!
因此对于什么换算的大道理请大家别白费了,孩子学起来不理解,很吃力,咱们教的也上火,不见效果,换种语言和方式也可以达到我们的效果。
So let us not waste any time on the logic of conversion. The child learns not to understand, is struggling, and we teach to be angry, not to see the effect, and to change the language and the way we do it.
一、对于单一单位的换算
Conversion to a single unit
对于单一的单位换算我们利用一句儿歌来教给学生:大变小,长尾巴,加一个0就好啦;小变大,去尾巴,把0去掉就长大!(小单位变大单位的时候让孩子们联想小蝌蚪变成青蛙的样子,大单位变成小单位的时候让孩子们联想青蛙生小蝌蚪的样子)
For a single unit, we use a child song to teach students: big, small, long tail, plus zero; small, big, go to tail, drop zero and grow!
如:7元=()角,从元变成角是大单位变成小单位,就是“长尾巴”,在7的后面加一个0就可以了。
For example: 7 yuan = () corner, from a dollar to an angle is a large unit to a small unit, i.e. a “long tail”, with a zero after 7.
30分=()角,是从小单位变成大单位,去掉尾巴0就可以了!如果出现跨级换算的时候,就是分换算成元,或者元换算成分,那就去掉或者加上2个0就可以了!
30 points = () from a small unit to a large unit, drop the tail by 0! If there's a transgrade conversion, it's a fraction, or a meta-conversion component, drop it or add two zeros!
二、对于两个单位转换成一个单位和一个单位转换成两个单位
II. Conversion of two units into one unit and one unit into two units
其实很简单,只要孩子们记住哪个单位大,哪个单位小,谁和谁相邻就可以了。(简单说就是爷爷、爸爸和孩子的关系)
It's very simple, as long as the children remember which unit is big, which unit is small, and who is next to whom.
在一个单位的两位数中间加上比自己大的相邻单位,或者去掉两个单位中间的大单位就可以了。
It is sufficient to add a larger adjacent unit to the two digits of a unit or to remove a large unit from the two units.
如:1元3角=()角,两个单位变成一个单位,把两个单位中的大单位“元”去掉就实现换算了。
For example: 1 dollar, 3 corner = () corner, two units become one unit, and conversion is achieved by removing the large units of the dollar from the two units.
28分=()角()分,一个单位变成两个单位,就把两位数拆开十位放在大单位里,个位放在小单位里就好了。或者说在2和8中间添上分的相邻大单位“角”就可以了。
28 points = () corner () and one unit becomes two units, and the two numbers are split into ten large units, one in a small unit. Or a large adjacent unit with a split between two and eight can be added.
三、对于人民币的简单运算
III. Simple calculation of the renminbi
用双手配合进行简单的分解运算:元加减元,角加减角,分加减分
Simultaneous decomposition with hands: meta plus minus, angle plus minus, fraction plus minus
如:3元5角+4元3角=()元()角,用两只手指头按住相同单位的数字进行运算。3元+4元=7元,5角+3角=8角,因此答案就是7元8角。减法亦如此!
For example: $3.50 + $4.3 = () won () angular, using two fingers to hold the same number in the same unit. $3 + 4 = $7, 5 + 3 = 8 corner, so the answer is $7.8. The same is true for subtractions!
如果出现了缺单位的情况,如:7角6分+2角=()元()角,第二个加数上就缺少单位“分”。这时只要告诉孩子们把6分直接写上,因为6分没有被加减所以没有变化,直接写到最后的结果里就好了。
In the case of missing units, e.g.: 7.0pm + 2pm = () dollar () corner, there is a lack of unit “points” on the second add-up. This is done by telling the children to write six points directly, since six points have not been added or reduced so there is no change, and it is better to write them directly to the final result.
对于人民币的计算而言,退位的减法应该是最难理解的!好多家长给孩子讲解退元换角、退角换分的方法,但是孩子们对于换算方面还存在一定的困难,因此在退位的过程中孩子们往往会在难以理解的换算上出错。因此我给孩子们讲解了以下三种方法:
The most difficult way to calculate the renminbi is to deflate. Many parents explain to their children the ways in which they can refloat and reflection, but children still have some difficulty in converting, so they often make mistakes in conversions that are difficult to understand during the process. So I explained to the children the following three ways:
1跨栏法
Cross-column method 1
如:5元3角-2元7角=()元()角,3角不够减7角怎么办?没有关系,让5元中的1个小家伙“跨栏”,跨过“元”,变成4元1,后面的3角照着抄下来,于是就成了4元13角,这样再进行计算就简单了!
For example: $5.3-2.7 = () Yuan, what if the 3 is not minus 7? It doesn't matter that one of the 5 small guys crosses the bar, crosses the dollar, becomes $4.1 and then the 3rd is copied down, and it becomes $4.13, so it's easy to calculate!
又如:7元-3元4角=()元()角,因为“元找元、角找角、分找分”,而7元里没有“角”怎么办?先把7元变成7元0角,之后在进行跨栏,再让7里面的一个小家伙进行跨栏,变成6元1,后面的0角照着抄下来,于是就成了6元10角了,这样就可以计算了。
Again, like: $7-3.4 = () the corner, because the dollar is looking for the dollar, the corner is looking for the corner, the corner is split, and there is no corner in the seven. What if there is no corner in the seven? First you turn the seven dollar into an angle of $7.0, then you cross the bars, and then you let one of the seven little ones cross the column, and it becomes $6.01, and then the zero in the back is written down, and it becomes $6.10, so that you can count it.
在跨栏的过程中一定要孩子们记住,只能有一个小家伙跨栏,一个栏不能大家都挤着跨,那样不但危险而且也违反比赛规则,孩子们对此记得比较牢固,另外先把那个跨栏的小家伙写在栏后面再把剩下的小尾巴抄下来,这样换算的困难便迎刃而解!
In the cross-bar process, it is important for the children to remember that there's only one little guy who crosses the bar, one that doesn't crowd everyone, that's not only dangerous, but also against the rules of the game, which the children remember more strongly, and then write down the little guy who crosses the bar behind the bar and then copy the rest of the tail, so that the difficulty of translating is solved!
2打怪物法
Two dozen monsters.
大家都知道要打败许多的怪物应该先把大怪物打败后才有可能获胜!所以在进行人民币的退位计算的时候也可以用这样的方法,先把大怪物打跑,再打跑小怪物。
Everyone knows that many monsters should be defeated before the big ones are defeated. So when the renminbi is de-positioned, it is possible to beat the big ones first and then the little ones.
如:5元-4元3角=()元()角,先用5元减掉4元,还剩下1元,之后再用剩下的1元减掉“小怪物”3角,还剩下7角。这样的方法不太适用于大单位相差较多的题型,因为相差较多剩下的就比较多,一般用于解决相差在1元以内的退位减法计算。
For example: $5-4.3 = () yuan, minus 4 with $5, leaving 1 dollar, then minus 3 with the remaining $1, leaving 7 cents. This method is not very suitable for large units with more differences, as the remaining difference is greater, and is generally used to settle the subtraction of less than $1.
3去掉大单位法
Three, take out the big unit code.
这种方法比较适合于单位相同的退位减法,并且计算能力较好的孩子,因为在前面的学习中我们已经知道了大单位换算成小单位的时候只要把大单位去掉就好。比如说7元3角,去掉大单位“元”,就变成了73角了,这样在相同单位的退位减法计算中就可以把人民币的计算转化成100以内的减法计算了。
This method is more appropriate for the same unit regression and for children with better computing skills, because we already know in previous studies that when larger units are converted into smaller units, it is better to remove larger units. For example, seven dollars, three cents, and then the larger unit, three cents, becomes 73 centimeters, so that in the same unit's regression calculation, the renminbi's calculation can be converted into a reduction of less than 100 cents.
如:3角4分-1角7分=()角()分,去掉大单位变成34分-17分=17分,最后再转变成1角7分。由于这样做需要转化两次,并且孩子们对两位数减两位数还不是很熟悉,因此我不是很建议大家运用这种方法,只要了解一下就好!
For example: 3pm - 1pm - 7pm = () Corner () to remove large units to 34p - 17pm and then to 1p 7pm. Since this takes two transformations and children are not very familiar with double-digit reduction, I am not very well advised to use this method, as long as I understand it.
在人民币的计算上,熟练掌握最基本的换算,还有不退位的加减,能够根据数学信息提问题并且正确解答,至于退位、进位的减法和加法孩子们能掌握多少就掌握多少吧,不希望孩子们还有各位家长朋友为此太过牵扯精力。
In the calculation of the renminbi, mastery of the most basic conversions, and non-diversional additions and reductions, the ability to ask questions based on mathematical information and correct answers, as far as the children of the retreat, the subtraction of the entry and the additions are concerned, do not want the children and their parents and friends to be too involved.
但是“换钱”还是希望大家能够尽量掌握牢固,这可能是我们考试中难度最大的题型。下面就简单介绍一下学习这类习题的方法。
But “money for money” wants you to be as strong as you can be, which is probably the most difficult topic in our exams. Here's a brief description of how to learn about these subjects.
简单说就是:看清换成多大的钱,换多少,掰着手指头数一数!
Let's just say, let's see how much money, how much, and then we'll figure it out.
如:一张10元的可以换()张2元
If: 1 can be replaced with 1 can be replaced by 2
最后都要换成2元的,换多少呢?10元。所以就两个两个的数,数到10就好了,用了几根手指头就是用了几张钱。
It's gonna have to be two dollars in the end, how much? Ten dollars. So just two or two, count to 10, just a few fingers, just a few.
由于人民币的面值是5、2、1,因此孩子们只要掌握一个一个的数,两个两个的数,五个五个的数就好了!数到最后要换的钱就好,用了几根手指头就是用了几张人民币。
Since the value of the renminbi is 5, 2, 1, the children need only know one number, two two and five. Just count the final amount of money to be exchanged, with a few fingers and just a few yuan.
还有一种题型可能会比较麻烦,如:一张5元可以换成()张5角。需要先将5元换算成50角之后再进行数手指头的工作。
There is also a problem with a caption, for example: a $5 can be replaced by a five-point. You need to convert the $5 into a 50-point job before you can count your fingers.

小朋友们,大朋友们,大家好!欢迎大家来到每周图文分享系列,在一年级的数学学习中,有一项较为重要的知识点,那就是“人民币的换算”。很多试题中都会出现此类题型,而因为人民币换算丢分的小朋友,是因为没有掌握正确的方法,所以才会丢分,接下来,喵喵君就要为大家分享一年级“人民币的换算”的方法和技巧。跟随喵喵君一起看下去吧!
Friends, friends! Welcome to the weekly graphics-sharing series. In the first grade of mathematics, one of the more important points of knowledge is the conversion of the renminbi. This is the type of topic that happens in many of the subjects, and since little friends who lose their points because they don't have the right methods, they lose their points. Next, Jojo will share the methods and techniques of the first grade, the conversion of the renminbi. Go with him.
首先我们要知道的是,人民币的单位,分别是:元,角,分。(元是人民币最大的单位,分是人民币最小的单位。)
First of all, we need to know that the units of the yuan are: won, corner, fraction. (The yuan is the largest unit of the renminbi and the smallest unit of the renminbi.)
我们经常遇到这样的单位换算题,那就是:
We often encounter the problem of unit conversion, which is:
例题1:
Case 1:
7角=( )分
Angular 7 = ( ) minutes
40角=( )元
40 Corners = () Dollars
5角=( )分
5 angles = ( ) minutes
60分=( )角
60 minutes = ( ) Corner
解析:先来看7角=( )分,我们知道,1角=10分,所以7角就是7个10分,即7角=(70 )分;再来看一下第二道,40角=( )元,因为10角=1元,40角里有4个10角,所以40角=(4)元;第三道5角=( )分,跟第一道题同理,1角=10分,那么5角里就有5个10分,就是50分,即答案是5角=( 50)分;最后一道60分=( )角,因为 10分=1角,所以60分里有6个1角,即60分=( 6)角。
Disaggregated: First look at the seven corners = () we know that the one corner = 10, so the seven corners are seven tenths, that is, seven corner = (70); then look at the second track, 40 corner = () dollar, because the ten corner = one dollar and four corneres in 40 corner, so 40 corner = (4); third corner 5 corner = () point, which is the same as the first issue, 1 corner = 10 point, then there are five tenths in the five corner, that is, 50 point, the answer is 5 corner = (50); last line 60 corner = () corner, because the ten corner = one corner, so there are six corners in 60 corner, that is 60 point = (6).
方法就是:遇到每相邻的单位换算,大单位换算成小单位,“添”0,小单位换算成大单位“去”0。
The method is to convert large units into small units, “add” zero, and small units to “go” zero for each adjacent unit.
除了上面例题1这种较为简单的题型,还有一些较为复杂的人民币换算,就不能用上面的方法了,我们再来看看人民币换算其他类型的题型。
In addition to the simpler version of question 1 above, some of the more complex RMB conversions cannot be done using the above method. Let us look at RMB conversions to other types of captions.
例2:
Example 2:
1元7角=()角
$ 1.07 = () Corner
3元5角=()角
$3.50 = () corner
解析:先来看第一道,1元7角=()角,我们知道,1元=10角,1元7角等于多少角,就要把10角和7角相加,就是17角,即1元7角=(17)角;再来看第二道,3元5角=()角,1元是10角,3元就是30角,3元5角就用30角和5角相加,就是35角,即3元5角=(35)角。
Parsing: First, when looking at the corner, one dollar = ten corner, and one dollar = seven corner = how many angles, we know that the corner of one dollar = ten corner = one corner = seven corner, that is, 17 corner, that is, one dollar = seven corner = 17 corner; second route, three dollar = () corner, one dollar = ten corner, three dollar = thirty corner, three dollar = five corner, that is 35 corner, that is, three dollar = (35) corner.
方法是:遇到几元几角换算角,几元是几,十位就写几,几角是几,个位就写几。
The method is: to meet the corner of a few dollars, the corner of a few dollars, the number of ten, the corner of a few, the number of places.
学会了几元几角换算角的题型,我们再来看一下,角换算成几元几角的题型。
We've learned the angles of a few cents, so let's look at them again, and we've got the angles of a few cents.
例3:
Example 3:
23角=()元()角
Angular 23 = angular ($)
56角=()元()角
Angular 56 = angular ($)
解析:先来看23角=()元()角,我们知道,1元=10角,23角里有2个10角,1个3角,所以,23角就是2元和3角,即23角=(2)元(3)角;那56角=()元()角,又应该怎么换算呢?56角里有5个10角和1个6角,因为10角=1元,50角=5元,即56角=(5)元(6)角。
Parsing: First, look at the corner 23 = () won, we know that the corner 1 = 10, there are two tenths and one thirds in the corner 23, so that the corner 23 is two and three, i.e., 23 = (ii) and (iii); the corner 56 = (iii) and how should it be converted? The corner 56 has five tenths and one sixth, because the corner 10 = 1 dollar, the corner 50 = 5 dollars, i.e. 56 = (v) (6).
方法是:角换算成几元几角,十位是几,就是几元,个位是几,就是几角。
The method is: the angle is a few cents, the ten bits are a few bits, the bits are a few bits, the corner is a few.
我们本期的一年级易错题型分享到这里就结束了。茂喵喵准备好了更精品的易错题型在下一期分享中等着大家呦!如果您有疑问请关注茂喵喵,及时给我们留言哦!我们下期见!
This is the end of the first year of our current year's misperceptions. Shizuku is waiting for you in the next one. If you have any questions, please pay attention to Shizuku and leave us a message. I'll see you next time.
现如今,出境游已不再是啥稀奇事。春节小长假临近,不少人已经将出境游提上了日程。热衷于出国扫货的海淘大妈们蓄势待发,向往着阳光海滩的北方“踢踏”一族也早已经南下报名。世界那么大,假期那么长,我要去看看。
Now, it's no longer a surprise to leave the country. The spring vacation is approaching, and many people have put their journeys on the agenda. The women of the sea who are eager to leave the country are ready to do so, and the people of the North who are heading towards the sunny beaches have signed up for it. The world is so big, the holidays are so long, I'm going to see them.
眼看假期临近,身在公司却无心工作,隔壁工位的富婆姐姐啪啪啪摁着计算器盘算此次欧洲休假之行,那个13580英镑的香奈儿包包要用多少人民币,Dior、兰蔻、NATURA BISS这些怎么样都要扫荡一遍,哎准备个十万元左右够不够啊。。。
Looking at the holiday near, working in the company, the rich sister of the next job, puncturing the calculator for this European holiday, the sum of RMB 13580 for the Chanel bag, Dior, Lancón, NATURA BISS, all of which must be cleaned up and ready for 100,000 won or less.
咳咳,虽然小编沉(gen)迷(ben)工(mei)作(qian)没时间出境玩,但也实在不忍心看见你们抓耳挠腮算汇率的一副傻样儿,在此就种草一下给要出境的小伙伴们吧,上百度App,货币汇率问题,一句话解决。
Cough, while qian has no time to go abroad, it is hard to see you scratching the stupid exchange rate, so let's get some grass here for the little partners who are leaving the country, hundreds of degrees App, currency exchange rate problems, one word.
现在只需打开百度APP,点击页面下方中间位置的蓝色麦克风,说出你要查询的兑换内容,例如:13500.357美元等于多少RMB,3568.75日元等于多少RMB,页面自动跳转计算,查询结果一目了然,省去了自己手动搜索输入和计算换算的时间,简直不要太方便!
Now all you have to do is turn on 100 degrees of APP and click on the blue microphone at the middle of the page and say what you want to look for, for example: $13500.357 equals RMB, 3568.75 equals RMB, the page jumps automatically, and the search results are clear and save your time by manually searching for input and calculating conversions.
当然,也会不少人出境选择小众旅游地,小币种在实际的货币兑换过程中无法在国内银行直接兑换,比如越南盾这种东南亚货币,所以就需要将美元作为中转币去兑换当地的货币。打开百度App,以同样的方法语音搜索,比如“5845.66越南盾相当于多少美元”“22.37美元可以兑换多少埃及镑”,不管什么货币单位、不管数字有多刁钻,百度APP一秒出答案。
Of course, a lot of people leave the country to choose a small tourist destination, and the small currency cannot be exchanged directly in the domestic bank during the actual currency exchange process, such as the Vietnamese guilder, which means that the dollar needs to be used as a transit currency to exchange local currency. Open the 100-degree App, using the same means of voice search, such as “5845.66 Vietnamese guilders equal to how many dollars” and “22.37 dollars can be exchanged for how much Egyptian pounds”, regardless of the currency unit, regardless of how many numbers, the 100-degree APP will answer for a second.
怎么样,这个功能是不是很方便,上百度APP直接问货币兑换问题,出国游玩的货币兑换再也不用担心!另外,小编温馨提示一句:查好汇率去银行兑换的时候要记得提前预约哦!
How's it going? A hundred degrees of APP is asking about currency exchange. There's no need to worry about going abroad.
一年级数学下册:人民币换算专项练习!假期提前预热,考试不扣分
First grade maths entry: RMB conversion practice!
人民币作为我们日常的支付工具,不管是对生活还是对学习都有着不可或缺的作用,因此每个人都应该学习人民币之间的换算,因为这不仅仅是对基础的数学知识了解,更是我们需要掌握的生活常识。而在一年级数学下册第五单元当中,会专门针对人民币单位换算来进行学习,可是从平时同学们的学习情况来看,这部分知识一直都是重难点,在考试当中这类题型也是频频丢分,那么在假期同学们又该怎样地预热这部分知识点呢?
The renminbi is an indispensable tool for our daily payments, both for life and for learning, and everyone should learn how to convert between the yuan, because it is not just a basic knowledge of mathematics, but also a common sense of life that we need. In the fifth module of the next book of mathematics in the first grade, the renminbi is used specifically to convert units, but it is always hard to learn, and it is often lost in the examinations.
其实,人民币换算主要考察的还是孩子们的逻辑思维能力,以及对数学基本知识的掌握。像随着年级的升高,同学们在小学阶段还是学习到长度的换算、面积的换算、重量的换算等数学知识,而学习难度也是因此慢慢增长的,所以家长们也一定要引起重视,如果能在一年级就掌握好人民币换算等相关知识点,以及单位换算这方面数学思维的培养,那么对后续的数学学习帮助是会非常大的。
In fact, RMB conversion is primarily about the children’s logical thinking skills and their basic knowledge of mathematics. As the grade rises, students learn mathematics skills such as length conversions, area conversions, weight conversions, etc. At the primary level, the difficulty of learning is slowly increasing, so parents must also pay attention to the importance of acquiring knowledge points such as RMB conversion in the first grade, as well as the development of mathematical thinking in the unit.
人民币换算在小学数学的学习当中贯穿始终,鉴于此下面老师整理了,一年级数学下册人民币换算的专项练习题。希望家长们能替孩子打印收藏,并在假期提前预热,相信啃透掌握,这部分题型考试不会扣一分。
It is hoped that parents will be able to print the collection for their children and keep it warm in advance of the holidays, believing that they will not lose a point in the exam.

一年级下册数学:人民币换算专项训练10套,适用于任何版本
Next Grade Mathematics: 10 RMB Specialized Training, applicable to any version
在一年级下册数学中,人民币的认识是一个必学知识,并且试卷上的考题比较多,但由于书本上的介绍较少,孩子们平时又比较少接触,所以于人民币的认识感觉有点转不过弯来了。虽然基础的1角等于10分,1元等于10角都记得很扎实,可是应用在练习题上就开始犯糊涂了。
In the next book of mathematics in the first grade, the renminbi awareness is a compulsory knowledge, and there are more questions on the test papers, but because there is less presentation in the books and children are usually less exposed, there is a little bit of a twist in the renminbi perception. Although the base is 10 cents and 1 dollar is ten cents, it is well-recognized, but it is applied to practice subjects that are confused.
那临近期末,为了帮助孩子们在人民币的相关考题上不丢分,老师我就特意花时间整理了10套关于人民币换算的专项练习题,这份练习题资料适用于所有版本,无论你的孩子是人教版还是北大师版的教材都可以打印练习。
At the end of the year, in order to help the children keep their marks on the RMB test, the teacher took time to compile 10 special exercises on RMB conversion, which are available in all versions, regardless of whether your child is a humanist or a North Master's.
