**Introduction to Rational Numbers: **Before getting into the concept of Rational Numbers let’s recall that for two integers a, b, the sum a+b, difference a-b, product a*b are always integers. However, it’s not always possible for an integer to exactly divide with the other integer given. It means the result may or may not be an Integer. For instance, when 7 is divided by 4 the result is not an integer and it is a fraction.

Thus, it is necessary to extend the system of Integers so that you can divide any given integer by another integer other than zero. Let’s dive deep into the concept of Rational Numbers and related info such as Properties of Rational Numbers, Representation of Rational Numbers on a Number Line, Properties and Operations of Rational Numbers, etc.
