Question

verify communitative property of multiplication for the following pairs of the rational number 4/5 and -7/8​

Answer 1

GIVEN:

The rational numbers 4/5 and -7/8

TO VERIFY:

Commutative property in multiplication of rational numbers.

PROOF:

Let us multiply 4/5 and -7/8

In multiplication, we can multiply the numerator with numerator and denominator with denominator.

So, the product will be -28/40

After being simplified, -7/10

Then let us multiply, -7/8 and 4/5

Multiply by using the same method,

So, the product will be -28/40.

After simplification,

our answer is -7/10

If you observe the both cases, you may see that there is no change in answer even though we changed the terms. So, Commutative property of multiplication of rational number is verified.
