To further simplify a ratio, we follow the same procedure that we use for simplifying a fraction. The fraction form that represents this ratio is a/b. 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'. We use the ratio formula while comparing the relationship between two numbers or quantities. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books. For example, out of every 10 people, 5 of them like to read books. For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole.

The part-to-part ratio denotes how two distinct entities or groups are related.

One is part to part ratio and the other is part to whole ratio. The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
