Question

Use the associative property of multiplication to rewrite the expression, then simplify 7/10 (20/7)y

Answer 1

(7/10*20/7)y

2y (Simplified)

Explanation:

According to the associative property, no matter how you regroup three or more numbers in a multiplication, the product will not change.

Then, keeping this on mind, you can regroup the multiplication given in the problem above as following:

(7/10*20/7)y

When you simplify you obtain:

(140/800)y=2y
