Class 9 Maths Chapter 1 Solutions
Starting with the Number System, the first chapter of the Class 9 Maths textbook. This chapter starts with the basic knowledge of natural numbers, whole numbers, integers, and rational numbers as well as irrational numbers, and ultimately takes you to a point where you can distinguish them from each other and also accept the fact that all these numbers basically belong to a family of real numbers. To better your understanding of the number system we have come up with Class 9 Maths Chapter 1 Solutions. Here you can find solutions to all five exercises included in this chapter.
Topics covered in the chapter Number Systems are:
- Natural Numbers, Whole Numbers, Integers, and Rational numbers.
- How Rational numbers is a combination of Natural Numbers, Whole Numbers and Integers.
- How to find rational numbers between two given numbers.
- Finding rational numbers between two given rational numbers.
- Irrational Numbers and how they are different from rational numbers.
- Plotting of irrational numbers on number line.
- Rational and Irrational Numbers combine to form Real Numbers.
- Different types of decimal expansion of Rational and Irrational Numbers.
- Expressing a rational number with terminating and non-terminating decimal expansion in the form of p/q.
- The addition, subtraction, multiplication and division of rational and irrational number is irrational.
- The addition, subtraction, multiplication and division of two irrational numbers can be rational or irrational.
- Representation of numbers like √4.5 , √7.2 , √6.5 etc on a number line.
