Multiplicative inverse of 0/1 is
(a) 1
(b) -1
(c) 0
(d) not defined

Solution:

Given fraction is 0/1

Any number divided by 1 is the number itself

So the number is 0

Multiplication inverse or reciprocal for a number x, denoted by 1/x, is a number which when multiplied by x yields the multiplicative identity, 1.

So 1/0 is undefined

Therefore, the multiplicative inverse of 0/1 is not defined

✦ Try This: Multiplicative inverse of 1/3 is (a) undefined, (b) -1/3, (c) 3, (d) 1

Let the number be x

(1/3)x = 1

x = 3

Therefore, the multiplicative inverse of 1/3 is 3.
