# NCERT Solutions Class 8 Maths Chapter 1 Rational Numbers

NCERT solutions for class 8 maths chapter 1 rational numbers show us that the foundation of Mathematics is numbers. Depending upon their types numbers can be classified into real, whole, natural, rational, irrational, and complex numbers. In previous classes, kids were used to working with whole and natural numbers while solving equations. But what happens when they end up with a fractional notation as the answer? These solutions help us to answer this question in detail. Any number that can be expressed in the form of a fraction or p/q is termed a rational number. Further, the decimal expansion of such a number is either terminating or non-terminating and recurring. NCERT solutions class 8 maths chapter 1 elaborate on the various properties of rational numbers and how to successfully apply these concepts to solve problems.

With the help of the exercise questions that fall under the scope of this chapter, kids can gain an in-depth knowledge of rational numbers. Also, students get to revise the properties of whole and natural numbers while also learning how these concepts can be adapted to rational numbers. Thus, the class 8 maths NCERT solutions chapter 1 is perfect to give students a holistic understanding of rational numbers and their versatility. In this blog, we will take a closer look at the sub-topics covered under the NCERT solutions Chapter 1 Rational Numbers that may seem simple but are very necessary for children to know in order to succeed not only in class 8 but higher grades also and also you can find some of these in the exercises given below.

## List of Formulas in NCERT Solutions Class 8 Maths Chapter 1

NCERT solutions class 8 maths chapter 1 encompasses formulas that are essential for getting a deeper understanding of the mechanisms of rational numbers. Most of the formulas are associated with various properties. Apart from this we also see how to calculate the mean of two rational numbers so that we can find one rational number that lies between the given two numerals. Some important formulas and properties covered in NCERT solutions for class 8 maths chapter 1 are given below:

- Closure Property: a + b, a - b, a × b results in a rational number.
- Commutative property: a + b = b + a; a × b = b × a.
- Associative property: a + (b + c) = (a + b) + c; a × (b × c) = (a × b) × c.
- Distributive property: a × (b + c) = ab + ac; a × (b - c) = ab - ac.
