How do you know if a number is in proportion?
Approach: If four numbers a, b, c and d are in proportion then a:b = c:d. The solution is to sort the four numbers and pair up the first 2 together and the last 2 together and check their ratios this is because, in order for them to be in proportion, the product of means has to be equal to the product of extremes.

What is a ratio form?
The general form of representing a ratio of between two quantities say ‘a’ and ‘b’ is a: b , which is read as ‘a is to b’. The fraction form that represents this ratio is a/b. To further simplify a ratio, we follow the same procedure that we use for simplifying a fraction. a:b = a/b.
