Question

Explain how you can use the Associative Property to evaluate (7x50)x4.

Answer 1

(7x50)x4 = 1400

Explanation:

It is given that (7 x 50 ) x 4

This is the form of associative property.

This can be expressed as, 7 x( 50 x 4)

Result of both are equal.

That means we ca write,

(7 x 50 ) x 4 = 7 x( 50 x 4)

LHS = (7 x 50 ) x 4

RHS = 7 x( 50 x 4)

Evaluate LHS

LHS = (7 x 50 ) x 4 = 350 x 4 =1400

Evaluate RHS

RHS = 7 x( 50 x 4) = 7 x 200 = 1400

Therefore RHS ans LHS are equal
