## FAQs on RD Sharma Class 7 Solutions Chapter 9 - Ration And Proportion (Ex 9.2) Exercise 9.2

1. What is chapter 9 of Ratio And Proportion of RD Sharma Class 7 Solutions?

We apply the concept of ratio and proportion in our daily lives, such as in business when dealing with money or when cooking any cuisine, for example. The concepts of ratio and proportion are sometimes misunderstood by students. Students will have a better understanding of these two concepts by reading this article, which includes additional solved examples and questions.

This section delves into the definitions of ratio and proportion. Both of these principles are crucial in mathematics. There are many examples in real life where the concept of the ratio is highlighted, such as the rate of speed (\[\frac{distance}{time}\]) or the price (\[\frac{rupees}{meter}\]) of a substance, etc.

Proportion is a mathematical expression that states that two ratios are equivalent. For example, the time it takes a train to travel 100 kilometers per hour is the same as the time it takes to travel 500 kilometers in 5 hours. For example, 100 km/hr = 500 km/5 hours.

2. Can you summarize RD Sharma Class 7 Solutions Chapter 9 - Ratio And Proportion (Ex 9.2) Exercise 9.2?

Yes, it can be summarized although you should definitely consider the chapter solutions by RD Sharma.

The relationship between the amounts of two or more objects is defined by the ratio. It's used to compare the same-kind quantities.

It is considered to be in proportion if two or more ratios are equal.

There are two distinct ways to express the proportion. Either an equal sign or a colon symbol can be used to represent it. (For example, a:b = c:d or a:b:: c:d)

It has no effect on the ratio whether we multiply or divide each term of the ratio by the same number.

If the ratio between the first and second amounts is identical to the ratio between the second and third quantities, the quantities are said to be in continuing proportion.

If the ratio between the first and second amounts is identical to the ratio between the third and fourth quantities, the four quantities are said to be in continuing proportion.

3. What are tips and tricks to solve Class 7 Chapter 9 Ratio and Proportion? What are the points I should remember?

Following are the Tips and Tricks for Solving Ratio and proportion questions-

The only thing that can be compared is two quantities with the same units.

Only if the two ratios are equal are they said to be in proportion.

We may also use the cross-product approach to see if two ratios are equal and generate a proportion.

Important Notes to keep in mind about Ratio and proportion-

It makes no difference if we multiply and divide each term of a ratio by the same number.

If the ratio between the first and second amounts is identical to the ratio between the second and third, the three quantities are said to be in a continuous proportion.

Similarly, in a continuous proportion of any four quantities, the ratio between the first and second is equal to the ratio between the third and fourth.

We can write ratio and proportion in two ways: with an equal sign, as in \[\frac{a}{b} = \frac{c}{d}\], or with a colon, as in a:b = c:d.

(the fractions \[\frac{a}{b}\] and \[ \frac{c}{d}\] are the same)
