Numbers 数字

Teacher：Today we’ll study numbers. What’s this number?
今天我们来学习数字。这个数字是多少？

Student：It’s one hundred and forty。
是140。

Teacher：Yes. Is it an even number or an odd number?
对。那它是偶数还是奇数？

Student：Well, a number that can be divided by two is an even number, so it’s an even number。
嗯，一个若能被2整除的就是偶数，所以它是偶数。

Teacher：OK. Let’s look at the next one。
好的。赞美来看下一个数。

Student：This figure is zero point five. It’s a decimal number。
这个数是0.5，是一个小数。

Teacher：Do you know how to change the decimal into a fraction?
你知道怎么把这个小数转化为分数吗？

Student：Yes. The number is one half。
知道，是1/2。

Teacher：Now pick two numbers between one and ten, including decimal numbers and fractions, then add, subtract, multiply or divide them as you like. If there are decimals in your answer, round them up to the nearest whole number。
现在从1到10之间挑选两个数，包括小数和分数，然后随意进行加、减、乘、除运算。如果的出来的答案是小数，就四舍五入到最接近的整数。

Student：Nine minus six is three. Four multiplied by two equals eight. Zero point three six plus one point seven five equals…
9减6等于3.4乘以2等于8 。0.36加1.75等于...

Teacher：Two point one one. Rounding it off to the nearest whole number gives you two. It’s easier to add it all up if you use whole numbers。
2.11。四舍五入到最接近的整数是2。如果你用整数相加要容易些。

Student：I get it. Thank you。
我知道了，谢谢老师。
