A reciprocal is one of a pair of numbers that when multiplied with another number equals the number 1.

For example, if we have the number 819/1306, the multiplicative inverse, or reciprocal, would be 1 ÷ 819/1306 because when you multiply 819/1306 and 1 ÷ 819/1306 together, you get 1

Reciprocal (or) Multiplicative Inverse is 1306/819
