Get chapter-wise RS Aggarwal Class 6 Maths solutions.

Introduction to Ratio: The chapter begins with an introduction to ratios. A ratio represents the quantitative relationship between two or more quantities and is expressed in the form of a/b, where 'a' and 'b' are non-negative numbers.

Equivalent Ratios: Students learn about equivalent ratios, which have the same proportion or comparison between quantities but may have different values. They practice finding equivalent ratios by scaling up or scaling down the given ratio.

Comparison by Ratio: The chapter covers how ratios are used to compare quantities of similar or different types. Students learn to apply ratios to compare items like money, weight, length, etc.

Introduction to Proportion: Students understand the concept of proportion, which represents an equation of two equal ratios. They learn that in a proportion, the product of the means is equal to the product of the extremes.

Solving Proportions: Students are taught how to solve proportion problems by cross-multiplication or finding the value of the unknown variable.

Application of Ratios and Proportions: The chapter includes various word problems and real-life situations where ratios and proportions are applied to find missing quantities or compare values.

Unitary Method: The unitary method is introduced as a practical approach to solving problems involving ratios and proportions. It involves finding the value of a single unit and then applying that unit to find the desired quantity.
