Class 8 Maths Rational Numbers Introduction

Introduction to Rational Numbers

A number which can be written in the form of p/q, where p and q are integers and q ≠0 is called a rational number. Numbers written in fraction are rational numbers.

  • -2/3
  • 6/7
  • -3/1
  • 4/0 is an undefined number and hence not a rational number.

For example, if there are 10 chocolates to be divided into 4 children, it is not possible to give 3 complete chocolates to each one of them. But, if 2 chocolatesare halved, then there will be 4half pieces and 8 full pieces of the chocolates. So each child would get 2 full pieces and 1 half piece
