Knowing 6 X 6 = 36 will help you solve which of the following problems?

• 36 ÷ 6 = 6

• 6 X 36 = 6

• 36-6 = 30

• 12 + 4 = 16

If 9 X 5 = 45 then which of the following is an inverse problem?

• 9 ÷ 5 = 14

• 45 ÷ 9 = 5

• 5 X 9 = 14

• 14 - 5 = 9

Knowing 8 X 7 = 56 will help you solve which of the following problem?

• 8+7=15

• 15-7=8

• 56 ÷ 7 = 8

• 15+8=23

What are both inverse problems for 9 X 8 = 72 ?

• 9 + 8 = 17 and 8 + 9 = 17

• 9 X 8 = 72 and 8 X 9 = 72

• 72 - 9 = 63 and 72 - 8 = 64

• 72 ÷ 9 = 8 and 72 ÷ 8 = 9

Which equation shows the inverse operation of:

8 x 3 = 24
