Answer 1

1

The rational number 1 is the multiplicative identity for rational numbers. if × =1. Rational numbers can be represented on a number line

Answer 2

Answer:

1

The rational number 1 is the multiplicative identity for rational numbers. if × =1. Rational numbers can be represented on a number line.

Step-by-step explanation:

Multiplicative identity: One is the additive identity for Rational, natural, whole numbers and integers, since multiplying it to them does not change the result. Hence, 1x a = ax1 = a, where a can be rational number or natural number or whole number of integer.

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.

For rational numbers, natural numbers, whole numbers, and integers zero is the additive identity and 1 is the multiplicative identity.
