In mathematics, reciprocal, or the multiplicative inverse, is a number or term that is related to another number or term be the relationship that when both are multiplied together, the product is one. Thus, 1/3 and 3 are reciprocals of each other because 1/3× 3 = 1. Similarly, the reciprocal of a number (n) is 1 divided by the number (n); the reciprocal of n is 1/n. Thus, the reciprocal of 3 is 1/3; of 3/2 is 1÷ (3/2)= 2/3, and of a/b is b/a.
If a number a is the reciprocal of the number b,then b is the reciprocal of a. The product of a number and its reciprocal is 1. Thus, 3× 1/3 = 1, (3/2)× (2/3) = 1, and (a/b)× (b/a)=1.
Reciprocals are used frequently throughout the many fields of mathematics. For example, they are used to make division easier when dividing by fractions. For example, 8 divided by 3 is the same thing as the operation 8 times 1/3.

Bilateral; two-sided; mutual; interchanged.
Reciprocal obligations are duties owed by one individual to another and vice versa. A reciprocal contract is one in which the parties enter into mutual agreements.
Reciprocal laws are statutes of one state that give rights and privileges to the citizens of another state if that state extends similar privileges to the citizens of the first state. A common example is the Reciprocal Enforcement of Support Act, which is a uniform law adopted in a majority of jurisdictions, by which a tribunal in the state where a wife or mother resides is able to commence proceedings for child support against a husband or father who resides in another state.

The reciprocal of a number is 1 divided by the number. Thus the reciprocal of 3 is 1/3; of 3/2 is 1 ÷ (3/2)= 2/3, of a/b is b/a. If a number a is the reciprocal of the number b, then b is the reciprocal of a. The product of a number and its reciprocal is 1. Thus, 3 × 1/3 = 1, (3/2) × (2/3) = 1, and (a/b) × (b/a) = 1.
