What Are Ratios and How Do You Use Them?

TL;DR

Ratios are a method of comparing two or more quantities and are typically expressed as 'a:b'. It is important to ensure that the units of the quantities being compared are consistent, and ratios can also be simplified or represented as fractions for easier interpretation.
