# Reciprocal

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.
