Introduction

Ratios :-

The ratio is used to compare two quantities. These quantities must have the same units.

The ratio is represented by “ : ”, which is read as “ to ”. We can write it in the form of “fraction”.

Example

Write the ratio of the height of Sam to John, where Sam’s height is 175 cm and john’s height is 125 cm.

Solution

The ratio of Sam’s height to John’s height is 175 : 125 = 7 : 5.

We can write it in fraction as 7/5.
