Question

(b)For any rational number ‘a’, if a x 1 = a, then 1 is called the ________.

Answer 1

Multiplicative Identity

For any rational number 'a', if a × 1 = a, then 1 is called the multiplicative identity.

Multiplicative Identity:

The multiplicative identity is defined to be a number which when multiplied by another number or multiplied with another number, gives the same number as the result.

That is, a × b = b × a = a, where b is the multiplicative identity.

However, for our purpose, 1 is the multiplicative identity because when 'a' is multiplied by 1, 'a' is the result itself.
