## FAQs on RS Aggarwal Solutions Class 7 Chapter-8 Ratio and Proportion (Ex 8C) Exercise 8.3

**1. Why ratio and proportion are included under the same topic?**

Ratio and proportion are related to each other. One cannot be clearly understood without the other with the concept of proportion more dependent upon the ratio concept. They both express the same information with the ratio determining the expression and the proportion with the equation. However the ratio and proportion have to represent the same relationship and only then the ratio will be proportional. Proportion is a way ahead of ratio, it deals with those ratios which are equal to each other. This gets clear by the way of representation. The ratio is represented by a single colon between the compared quantities while the proportion is represented by double colons between the compared ratios.

**2. How is fraction related to ratio and proportion according to RS Aggarwal Solutions Class 7 Chapter-8 Ratio and Proportion (Ex 8C) Exercise 8?**

The topic ratio and proportion is an extension of the topic of fractions. Fraction always determines a part of the whole, often represented by the numerical value of the part divided by the numerical value of the whole where the value of the whole can never be zero. The ratio on the other hand determines the relation between the two quantities which may or may not be a part of the whole. Proportion also bears some similarity with the concept of proportion representing the quantity of something which actually determines the part of a whole amount while fraction is just the part of the whole.
