## FAQs on Important Questions for CBSE Class 7 Maths Chapter 7 - Comparing Quantities

1. How to Quickly Grasp the Sums Based on the Concept of Interest?

There are mainly two subtypes of interest and sums are based on various operations on them. These two variants are simple interest and compound interest. Although compound interest is more complicated than simple interest and it is taught in higher standards. You need to learn all the formulas related to simple interest and solve the sums in different procedures. The main formula of simple interest is SI= (PxRxT)/100. Here, P is the principal amount, R denotes the urate of interest and T denotes time. Now, you have to derive either of these three while doing a sum on interest belonging to the exercises of Chapter 7.

2. What is the Right Way to Learn the Sums on Decimals Easily?

The right way to learn the sums on decimal is simple as you need to study the basic concepts of decimal units at first. You can differentiate between integers and decimal numbers and learn how to denote decimal numbers verbally. In the next step, you will come to know about adding two decimal numbers, subtracting them, or multiplying and dividing. Furthermore, decimals’ advanced problems relate to conversations where you have to learn to change the decimal numbers to fractions and work with both decimals and percentages. As per the sums on percentage are concerned, you can learn the basic mathematical works with them like the decimals.

3. What do you mean by comparing quantities?

Two values must have the same units to be compared, and two ratios can be compared by turning them into like fractions. We say the two provided ratios are comparable if the two fractions are equal. Comparing Quantities refers to the quantitative relationship between two quantities that indicates their respective sizes. It is merely a tool for comparing amounts. It has multiple benefits and uses in our day to day life, and hence it is very crucial to learn about the concepts related to it.

4. What is the use of comparing quantities Class 7?

To compare is to perform an analysis between the differences in numbers, amounts, or values in order to validate if one quantity is larger than, lower than, or equal to another. We can define or determine how much a number is bigger or less by comparing. We may also compare decimals and fractions in this way. If you want to know how much something weighs, you may do that by measuring it against another standard or reference unit.

5. What is the use of percentage Class 7?

To make computations easier, we utilise percentages. Working with parts of 100 is considerably easier than working with thirds, twelfths, and so on, especially since many fractions lack a precise (non-recurring) decimal counterpart. When the number of individuals in the groups are not the same, it is critical to compare using percentages. Comparing counts and percentages are similar when the number of persons in the categories is the same. Hence, using percentages can come in handy in multiple operations and can help address different confusions and problems.

6. What does it mean by interest in maths?

The cost of borrowing money is interest, which is paid to the lender as a charge for the loan. Simple interest is a fixed proportion of the principal amount borrowed or lent that is paid or received over a period of time. The amount of money paid for the use of someone else's money is known as interest. It is a very crucial agent in transactions carried out in today’s market. Hence it is important to have a good knowledge of its concepts, processes and uses.
