The mathematical term 'ratio' defines the relationship between two numbers of the same kind.

The relationship between these numbers is expressed in the form "a to b" or more commonly in the form: a : b A ratio is used to represent how much of one object or value there is in relation to another object or value.

In order to write a ratio in the form '1:n', you must make the left-hand side of the ratio equal to 1.

Alternatively, in order to write a ratio in the form 'n:1', you must make the right-hand side of the ratio equal to 1.

(a) - For the ratio , you can make the left-hand side of the ratio equal to 1 by dividing both sides of the ratio by 4: = 4/4 : 20/4 = 1:5 Therefore, the ratio can be written in the form 1:5 (b) - For the ratio , you can make the right-hand side of the ratio equal to 1 by dividing both sides of the ratio by 20: 4: 20 = 4/20 : 20/20 = 0.2:1 Therefore, the ratio can be written in the form 0.2:1 Although ratio problems may appear complex at first, with practice you will find that they are relatively simple to solve.

When tackling ratio problems, it is advisable that you revise the main principles of 'Arithmetic with Fractions'.

This is because fractions and ratios share many fundamental properties.

Once you understand these properties, you can use ratios to solve various real-world problems.
