Question

What are the identity for the addition an multiplication of rational number

Answer 1

Additive identity is 0.

Multiplicative identity is 1.

Answer 2

Answer:

The additive identity of rational number is 0

The multiplicative identity of rational number is 1.

Step-by-step explanation:

Additive identity: Zero is the additive identity for Rational, natural, whole numbers and integers, since adding it to them does not change the result. Hence, 0 + a = a + 0 = a, where a can be rational number or natural number or whole number of integer.

Multiplicative identity: 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.
