Question

в двух коробках одинаковое колличество скрепок. из первой коробки взяли 12 скрепок а во вторую коробку положили 20 скрепок. На сколько меньше стало скрепок в первой коробке чем во второй?

Answer 1

когда забрали из первой коробки 12 скрепок, в первой стало на 12 меньше, когда добавили во вторую коробку 20 то стало меньше еще на 20

20+12=32 в первой коробке стало меньше на 32 скрепки,чем во второй.

Answer 2

20+12=32

Answer 3

Problem Analysis

We have two boxes with an equal number of paper clips. From the first box, 12 paper clips are taken out, and then 20 paper clips are added to the second box. We need to determine the difference in the number of paper clips between the first and second boxes.

Solution

Let's assume that the initial number of paper clips in each box is x.

After taking out 12 paper clips from the first box, the number of paper clips remaining in the first box is x - 12.

After adding 20 paper clips to the second box, the number of paper clips in the second box becomes x + 20.

Therefore, the difference in the number of paper clips between the first and second boxes is (x - 12) - (x + 20).

Simplifying the expression, we get x - 12 - x - 20, which further simplifies to -32.

Hence, the number of paper clips in the first box is 32 less than the number of paper clips in the second box.

Answer

The number of paper clips in the first box is 32 less than the number of paper clips in the second box.
