Write a fact family with 8, 9, and 72.

8 x 9 = 72

9 x 8 = 72

72 ÷ 9 = 8

72 ÷ 8 = 9

Step-by-step explanation:

A family of operations is a group of number expressions (operations) that use the same numbers. In this case (multiplication and division), the family of operations consists of two multiplications and two divisions.

In the multiplications the total of groups is calculated (72). While the divisions calculate the amount of each group (8 and 9).

For numbers 8, 9 and 72 the fact family is:

8 x 9 = 72

9 x 8 = 72

72 ÷ 9 = 8

72 ÷ 8 = 9

Hope this helps!

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
