# RS Aggarwal Class 7 Solutions Ratio And Proportion

## RS Aggarwal Class 7 Solutions Chapter 8

The mathematical numbers which are used as a method of comparison between two things which are quantifiably similar in terms of units is called as a Ratio. It is represented with the “ : ” symbol and is useful as a metric of measurement for similar things. For example the weight of two bikes can be represented in a ratio form, by considering the different variables.

Weight of Bike A = 100 Kgs

Weight of Bike B = 120 Kgs

Ratio of Bike (A/B)= $\large \frac{100}{120}=\frac{5}{6}=5:6$

Proportions are metrics useful for comparing two or more ratios with each other. In order to check and ensure whether the distributions are equal, we use the concept of Proportions.
