## Introduction of Ratio, Proportion, and Unitary Method

The ratio is a comparison of two quantities. The ratio is written as a fraction. For example, the ratio of 5 to 10 is written as 5:10. Proportion is an equality between two ratios. For example, if there are three apples and four oranges in one hand and one apple and two oranges in another hand, then we say that the ratio of orange to apple is 2:3, which means that for every unit of apple, we get two units of oranges. The unit for both the apple and orange is the same, so we can say that the ratio of oranges to apples is 2:3.

Unit Method or Unitary Method is a way of finding a proportion when two ratios are given. It is done by finding the unit for each quantity in one of the ratios and then multiplying them across. If two ratios are given, then the first step is to find the unit for each quantity in one of the ratios and write them as fractions. For example, if three apples are given against five oranges, then write the orange as 1/5. Then multiply across to give 3x1/5=5. The proportion is 3:5.

This chapter is all about ratio, proportion, and the unitary method. In this exercise, we will be working on problems that involve these concepts. With the help of these concepts, students solve all kinds of problems which are related to this chapter.

## FAQs on RD Sharma Class 6 Solutions Chapter 9 – Ratio, Proportion, and Unitary Method (Ex 9.2) Exercise 9.2

1. What is the difference between a proportion and a ratio?

The unitary method can be used to solve proportions by finding a common unit for the two given quantities. The difference between a proportion and a ratio is that a proportion is an equation involving two equal fractions, while a ratio is an equation involving two non-equal fractions. Ratio questions are solved by cross multiplication, while proportions cannot be solved using this method and instead require the unitary method.

In a proportion, if there are two unknowns, x and y, relating to A and B, respectively, then the following equation is true: formula_1: where a is the smaller of A and B and b is the larger. If we have a ratio instead of a proportion, then this equation becomes formula_2: where x and y are the same quantities as in the proportion, but they represent the two different fractions in the ratio.

2. How to use the unitary method to solve ratio proportions questions?

The unitary method can be used to solve proportions by finding a common unit for the two given quantities. The difference between a proportion and a ratio is that a proportion is an equation involving two equal fractions, while a ratio is an equation involving two non-equal fractions. Ratio questions are solved by cross multiplication, while proportions cannot be solved using this method and instead require the unitary method. In a proportion, if there are two unknowns, x and y, relating to A and B, respectively, and solve the question.
