Question

Check commutative property of the following rational numbers: 4/7,8/9

Answer 1

Answer:

We know distributive property, a (b + c) = ab + ac

Therefore, -4/9 x (6/5 + 11/10) = (-4/9 x 6/5 ) + (-4/9 x 11/10)

LHS,

-4/9 x (6/5 + 11/10) = -4/9 x (11+12/10×5) = -4/9 x (23/10) = (-92/90)

RHS,

(-4/9 x 6/5 ) + (-4/9 x 11/10) = (-24/45 ) + (-44/90)= (-48-44)/90 = -92/90

Therefore, RHS = LHS, distributive property proved.
