FAQs on CBSE Class 8 Maths Chapter Wise Revision Notes 2024-25

1. How can I score good marks in CBSE Class 8 Maths?

It is not difficult to get good marks in Class 8 Maths. If you articulate the correct strategies and choose the right study materials, then you can become one of the top scorers in your class. Practice is the most important key to success in maths. In study materials, you should first focus on completing NCERT. After completing NCERT, you should begin revising your exam syllabus. For the best revision, choose CBSE Class 8 Maths Notes available on Vedantu.

2. How is a bar graph different from a double bar graph in CBSE Class 8 Maths?

In data handling, bar graphs and double bar graphs are very common. A bar graph is a graphical representation of a single set of data along bars of the same width and heights proportional to the data value. In a bar graph, you will see single bars one after the other. In a double bar graph, there is a graphical representation of two sets of data simultaneously. So, you see double bars next to one another which are used for comparison.

These solutions are available on Vedantu's official website(vedantu.com) and mobile app free of cost.

3. Which chapters are important to prepare for the exams in CBSE Class 8 Maths?

All the chapters in the NCERT book for Class 8 Maths are equally important. You should prioritize completing those chapters first that you find tough. Then, you can start practising chapters that are easier for you. Do not miss out on the examples. And, when you are revising, use Vedantu’s CBSE Class 8 Maths Revision Notes for revision. These notes have full chapters in a simple tone and are comprehensible, leaving out no topic.

4. What is regrouping in CBSE Class 8 Maths?

Regrouping, in simple words, is arranging the terms to make factorisation easy. For example, let’s take 2xy + 3 + 2y + 3x. We see here that factorisation is not easy. So, we arrange them into: 2xy + 2y + 3x + 3. This allows us to form the following groups: (2xy+3x) and (2y+3). Its factorisation will give the factors (2y+3) and (x+1). If you multiply (2y+3) (x+1), you will get the same answer, i.e, 2xy + 3 + 2y + 3x.

5. What is a rational number in CBSE Class 8 Maths?

Any number that can be written in the form of ab, where, a and b are integers (positive or negative number) and b is not equal to zero can be called a rational number. For example, -72, 25 etc. Since numbers like 7, 0, -3 etc, can also be expressed in the form of  ab, they are also rational numbers. So, integers, whole numbers, and natural numbers - all are included in rational numbers.
