Question

1). Multiplicative identity for rational number is *

Answer 1

We know that whole numbers are a subset of integers which in turn are a subset of rational numbers. Also, 1 is the multiplicative identity for rational numbers because the product of 1 and any rational number is the rational number itself.

Thus, 1 is the multiplicative identity for whole numbers, integers and rational numbers.
