# Multiplicative Inverse of Rational Number | Reciprocal of Rational Number

Every nonzero Rational Number a/b has its multiplicative inverse i.e,  b/a

In order to find Reciprocal or Multiplicative Inverse of any Rational Number, we simply reverse the Fraction i.e, the Numerator becomes Denominator, and the Denominator becomes Numerator
