Introduction

You can define Ratios as the mode for making the comparison between different quantities and for that you must ensure that the units of these quantities are the same. They define the relationship between two quantities having the same unit.

Ratios are often written in the form of fractions, then these fractions are further converted into the form of like fractions. In the case, these like fractions of two or more quantities comes to be equal we then say that the two ratios are now equivalent.

Eg: If the cost of the 5 pens is Rs 80, find out the exact cost of 20 pens.

Solution – The cost of 5 pens = Rs 80

Ideally, the Cost of 1 pen = 80 ÷ 5 = Rs 16

Hence, the cost of 20 pens = 20 × 16 = Rs 320.
