What is the ratio formula?

Ratio Formula

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.
