Question

Rewrite (9*12) 20 using the commutative law of multiplication.

a. (12*9) 20
b. (20*9) 12
c. (20*12) 9
d. (9*20) 12

Answer 1

The commutative law of multiplication allows us to rewrite (9*12) 20 as (12*9) 20. Hence, a) is correct.

Step-by-step explanation:

The commutative law of multiplication states that changing the order of the numbers being multiplied does not change the product. In this case, we have (9 * 12) 20. Using the commutative law, we can rewrite this expression as (12 * 9) 20. So the correct answer is option a, (12*9) 20.
