Answer 1

The multiplicative inverse of a number x is given by x-1, such that when it is multiplied by its original number, it results in value equal to 1. For example, the multiplicative inverse of 2 is 2-1 as it satisfies the expression: 2 x 2-1 = 2 x ½ = 1

It is also called as reciprocal of a number.
