Question

Let a, b, and c be three rational numbers where a=2/3, b=4/5 and c= -5/6
verify associative property of multiplication

Answer 1

Step-by-step explanation:

associative property under multiplication

(axb)xc=ax(bxc)

(2/3x4/5)x-5/6=2/3x(4/5x-5/6)

(8/15)x-5/6=2/3x(-20/30)

-40/90=-40/90

-4/9=-4/9

RHS=LHS

It's verified
