How to use the properties of rational numbers in the questions ?​

Answer 1

Commutative property

1. Addition

If any two numbers are added for example a and b the a+b=b+a

So addition is the commutative property for rational number.

2. Subtraction

For two rational numbers a and b, a-b ≠ b-a

It is not commutative for rational numbers.

3. Multiplication

For any two rational number a and b a*b = b*a

Multiplication is commutative for rational numbers.
