As children progress through KS2 they will learn more about fractions in Maths. As well as understanding the different values of fractions, in Year Four children will be exposed to smaller fractions such as twentieths. They will also learn how to go about calculating fractions of other numbers.
Fractions can be written more than one way. For instance ten twentieths could be written as 10⁄20 and it has the same value as 1⁄2 or 2⁄4. When you are calculating fractions of numbers you divide them by the number below the line and then times the answer by the number above the line. For example, to work out four twentieths of forty you divide 40 by 20, which is 2, then times two by 4 giving the answer 8.
