Question

Verify closure property and commutative property.
3/5 and -5/8

Answer 1

Step-by-step explanation:

closure property is when the product of two rational number ia also a rational number

3/5 x -5/8 = -15/40

it is a rational number

commutative property is when

a = 3/5

b = -5/8

and

a x b = b x a

let's prove it.

3/5 x -5/8 = -5/8 x 3/5

-15/40 = -15/40

LHS = RHS

Hence, verified.

I hope it helps you.
