In KS2 Maths children will come to understand how to use ratio to represent the relation between numbers. In Year Six children should be confident when converting ratios into fractions, and vice versa.
Ratio is the relation between two numbers or quantities. It is useful for showing the number of times one value contains or is contained within the other. For instance in the ratio 1:3, if 1 is sand and 3 is water, you would need three times the amount of water in relation to sand. Ratios are excellent tools which help us to visualise how different numbers of things compare to one another. They are also very similar to fractions. The ratios 1:3 and 2:3 can also be represented by the fractions 1⁄3 and 2⁄3
