Denominator – Definition with Examples

What is a Denominator?

In math, a denominator can be defined as the bottom number in a fraction that shows the number of equal parts an item is divided into. It is the divisor of a fraction.

Here, for instance, 4 is the denominator, meaning there are 4 parts altogether.
