## CBSE Class 8 Maths Chapter 13: Chapter Summary

In this chapter, Direct and Inverse Proportions, students will learn about Direct Proportion and Inverse Proportion, how they are derived, their application, and properties. Sometimes a change in the proportion of one quantity means a change in the proportion of the other. For example, when you buy more apples, you’ll have to pay more money. Similarly, if we increase the speed of a vehicle, the time that it takes to cover some distance goes down. The first is an example of direct proportionality and the second is an example of quantities that are inversely proportional.

Inverse proportion is the relationship between two variables when their product is equal to a constant value. When the value of one variable increases, the other decreases, so their product is unchanged. In contrast, directly proportional variables increase or decrease with each other.
