The numerator is the top number, the denominator is the bottom number.

The numerator shows how many pieces you are concerned with.

The denominator shows how many pieces the whole thing is split into.

On this exercise you need to change the fraction to match the shaded in circle.


If the circle is split into 10 pieces and 4 are shaded in but the fraction shows a denominator of 5 you need to find the equivalent number of 410 in fifths.

Look at the denominators: 10 and 5.

To divide the 10 to get a 5 you would use ÷ 2.

10 ÷ 2 = 5

You must do the same to the numerator: 4 ÷ 2 = 2

410 = 25

Adjust the numerator.
