Identify Fractions uses circles to demonstrate the meaning of numerator and denominator.
The following illustration was made by Identify Fractions With Circles Designer:
We will call a full circle a unit. This unit is divided into 3 equal parts. If we take the two colored parts, we have taken two of the three equal parts.
The top number 2 in the numeral is the numerator. The numerator tells us how many of the parts in the unit are to be taken.
The bottom number 3 in the numeral is the denominator. The denominator tells us the total number of equal parts into which the unit is divided. In this example there are 3 equal parts in the circle.
The line between the numerator and denominator is known as the fraction bar. It is also called the division bar.
You will enter the fraction because 2 of the 3 parts in the circle are colored.
