What is a reciprocal, as it relates to math?

Answer by  rjprelude (20)

A reciprocal is the mathematical term for taking a number and dividing it by one. For example, one eight, 1/8, is the reciprocal of 8. Basically, if you have a fraction and you reverse it by taking the numerator and switching it with denominator you will create the reciprocal.

To get a reciprocal of a fraction, just turn it upside down. For example, the reciprocal of 3/4 is 4/3. For mixed fractions, just convert it to an improper fraction. Then, switch numerator and denominator. For example, 2 1/3 = 7/3... now swap... answer is 3/7.
