Answer:
9 * 7 = 7 * 9 Communitive Property
4 * 3 = 3 * 4 C.P
5 * (6 * 4) = (5 * 6) * 4 Associative Property
7 * (2 * 8) = (7 * 2) * 8 A.P
12 * 3 = (2 * 3) + (2 * 3) Distributive Property
Explanation:
Most of your Homework involves no calculation at all.
For example,
9 * ? = 7 * 9 Both of them equal each other.
9 * ? = 63 So the ? is 7 so that they both equal 63.
The last problem you would have to solve.
