Is 1 the multiplicative identity of rational numbers give an example to justify your answer?

numbers, integers and whole numbers are non commutative under subtraction and division. Role of zero and one- 0 is the additive identity for rational numbers. 1 is the multiplicative identity for rational numbers.

What is multiplicative identity and additive identity?

Additive Identity and Multiplicative Identity are two different identity properties of numbers. Zero (0) is the additive identity and one (0) is the multiplicative identity for all the numbers such as whole numbers, natural numbers, integers, etc.
