Direct and Indirect Proportions: Introduction

Direct and Indirect Proportions is a chapter of class 8 mathematics that educates children about the direct and indirect proportional relationship between quantities. The basic concept is tested as an application-based question. To solve these problems, a student must have clear fundamentals.

‘ is used in mathematical terms as the proportionality symbol. For example, if the given condition with two quantities a & b states that a is proportional to b, then it will be represented as “a ∝ b”. If a is Inversely proportional to b, it will be denoted as ‘a∝1/b’

Direct and Inverse proportions are used to determine how the quantities and amounts are correlated with each other. If increasing one quantity increases the other, then the relation is Directly proportional. If increasing one quantity leads the other quantity to decrease, then the correlation between them is called Inverse proportion.

Class 8 children can refer to books like RS Aggarwal for solving good questions. A lot of FREE resources can be also found on Vedantu’s Official website and Youtube channel from where the child can benefit.  This helps students grasp the concepts better and do well in exams.

Direct and Indirect Proportions are high-scoring topics and students can score full marks with adequate practice.

4. When are 2 quantities a and b said to be in direct proportion?

Any 2 quantities, a and b,  are in direct proportion if the ratio of their corresponding values remains constant which means if 'a' increases, 'b' will also increase, and same if 'a' decreases, 'b' will also decrease.  This can be represented as a/ b = k, (where k is a positive number and the quantities a and b are said to change direction).
