Question

verify the commutative law for rational numbers
4/5 and 3/8​​

Answer 1

Answer:

Well, commutative property holds in rational no only in multiplication and addition.

a) Commutativity over addition.

4/5+3/8= 32+15/40= 47/40

and in the reversed order again

3/8+4/5= 15+32/40=47/40

b) Commutativity over multiplication

4/5 x 3/8= 12/40

and again in the reverse order

3/8 x 4/5 = 12/40

So I hope you understand it
