Johan's gift shop needs to mail 45 checks to the bank. If they can put 5 checks in each envelope, how many envelopes how does the shop need to use?

9 envelopes

Step-by-step explanation:

Divide the 45 checks into 9 groups of 5.

|   5   |   5   |   5   |   5   |   5   |   5   |   5   |   5   |   5   |

45 checks divided into 9 envelopes equals 5 checks per envelope

45 ÷ 5 = 9

Take away one group of 5 checks from the 45 checks. Then take away another group of 5 checks, and another, and another. When there are no more checks, count how many groups you took away. You can take 9 groups away from 45, so that is your answer.

To tell that the answer is 9 groups of 5 checks, follow these steps.

Look at the equation. 45 ÷ 5 = 9.

The amount of groups is what 45 ÷ 5 equals. What the 45 checks is divided by is the amount in each group.

This means that there are 9 groups of 5 checks.
