  To calculate one quarter of a number, we divide by 4.

# Fractions (Year 4)

As you go through KS2 Maths, you'll discover more about fractions. In Year Four, you'll learn about smaller fractions like twentieths and how to calculate them.

Fractions can be written in different ways. For example, 10 twentieths is the same as 10/20, 1/2, or 2/4. When you calculate fractions, divide the number by the bottom one and then multiply by the top one. For instance, to find four twentieths of forty, divide 40 by 20 (equals 2), then multiply by 4 to get the answer 8.
