What is Multiplicative Inverse?

In math, you can find the multiplicative inverse by inverting or flipping the numerator and denominator in a fraction. For example. the multiplicative inverse of 4/5 is 5/4. For a whole number, like 10, we first make 10 into a fraction by expressing it as 10/1 then we flip it to get 1/10 which is the multiplicative inverse or reciprocal of 10.
