Answer:

6 plus 6 is 12 and 6 plus 6 is 12 so you subtract which would be 6 positive

Step-by-step explanation:

When adding two numbers with like signs, add the values and keep the common sign. When adding two numbers with unlike signs, subtract the values and use the sign of the larger-valued number. Change the subtraction operator to addition and change the sign of the number that immediately follows.

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 th

Iteru [2.4K]

Answer: 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.
