Ratio is the relationship of two numbers of the same nature. It gives us a sense of direction; where thing are going and a sense of comparison between stuff
Ratio can be a single number, a percentage, a fraction

So when you need to compare, to have a wider look or just want fewer numbers to look at; think of using ratios
