Question

这数学怎么做？

1）The luncheon special at Little Jimmy's costs $4.89. The math club has $23.50 in its account. What is the greatest number of luncheon specials they can buy with money in their luncheon account?
2）A cd case is 0.375 in. thick. You can build a shelf that is at most 36 in. long. How many CD cases can you fit on the shelf?

Answer 1

23.5/4.89=4.80
4 is the greatest number of luncheon specials they can buy.

36/0.375=96
96 CD cases can be fitted on the shelf.

Answer 2

1）
23.5/4.98=4.8→4
So the greatest number of luncheon specials they can buy with money in their luncheon account is 4

2）
36/0.375=96
so I can fit on the shelf with 96 CDs

Answer 3

If you have learn division, the calculation is straightforward.

23.50/4.89 = 4.8

36/0.375=96

So 1). They can buy 4 luncheon specials.
2). The shelf can fit 96 CD cases.

Answer 4

1） 23.5/4.89=4.8 根据题意可买特价午餐4个。
2） 36/0.375=96 书架上可放CD盒96个。
