Question

Use the dissociative property of multiplication to find the products and match the correct pairs.

• A. $435$
• B. $7644$
• C. $4536$

Answer 1

$87\times 5=(80+7)\times 5=(80\times 5)+(7\times 5)=\left(400\right)+\left(35\right)=435$


$182\times 42=182\times (40+2)=(182\times 40)+(182\times 2)=\left(7280\right)+\left(364\right)=7644$


$63\times 72=63\times (70+2)=(63\times 70)+(63\times 2)=\left(4410\right)+\left(126\right)=4536$
