A fraction describes part of a whole. Let’s look at a pie cut into 4 equal slices. The pie is the whole and we’ve divided the whole into 4 equal parts.

If 1 slice is eaten and 3 are left, what fraction of the pie is left?

The bottom number, known as the **denominator**, shows the total number of slices. The top number, or **numerator**, shows the number of parts we’re talking about.
