Multiplicative inverse calculator tool is the reciprocal of a number. For example say 4 is the given number then the multiplicative inverse or reciprocal of that number is . If we multiply a number with its multiplicative inverse the result is always 1. Hence 1 is called as multiplicative identity.

**Example 1:** Find the multiplicative inverse of 71, and

71 is an integer. But it can be written as a fraction. 71 is equal to

Multiplicative Inverse of 71 is

Multiplicative Inverse of is =

Multiplicative Inverse of is =

Check:

The product of a number and its multiplicative inverse should be 1.

71 x = = 1

x = = 1

x = = 1

**Example 2:** Find the multiplicative inverse of 2 - and simplify your result.

Here 2 - do not have a denominator. We can write this into a fraction with denominator as 1. Now we get . Multiplicative inverse of is .

Inorder to simplify this , multiply the numerator and denominator with the conjugate of

2 - . The conjugate is 2 + .

x = = = 2 +.
