7-86.

Recall that inverse operations “undo” each other. Write the inverse operation for each situation below.

Addition and subtraction are inverse operations.
For example, adding 4 and then subtracting 4 takes you back to your original number.

Multiplication and divsion are also inverse operations.
For example, multiplying a number by 4 and then dividing by 4 takes you back to your original number.

1. Add $\frac { 3 } { 4 }$.

$\text{Subtract}\ \frac{3}{4}.$

1. Subtract $1\frac { 2 } { 3 }$.

If subtraction and addition are inverse operations, how much do you have to add?

1. Divide by $8$.

Multiply by 8.

1. Multiply by $12$.

If multiplication and division are inverse operations, how much do you have to divide by?
