Read More →Multiplicative inverse When we divide 1 by the number, we get “Reciprocal” of the number. The reciprocal = 1/number Example- The reciprocal of 5 is 1/5 When we multiply a number by its “Multiplicative Inverse” we get 1. Simply the product of a numbers and its reciprocal is 1, then each number is known as Reciprocal […]
