Answer:

(b) 15 over 56 times a squared

Explanation:

You want the product of (5/8a) and (3/7a).

Multiplication

The commutative and associative properties of multiplication help you find this product:


(5)/(8)a\,*\,(3)/(7)a = \left((5)/(8)\cdot(3)/(7)\right)* (a\cdot a)=(5\cdot3)/(8\cdot7)a^2=\boxed{(15)/(56)a^2}
