**What is a Rational
Number?**

The definition of a rational number is “A number which can be
expressed in the form of p/q or fraction where p and q are integers
and q ≠ 0 is a **Rational Number**.

**Examples of Rational
Numbers**

All the integers and decimal numberes can be expressed in the form of p/q or fraction of two integers. For example 0 = 0/1, 1 = 2/2, -2 = -4/2, 0.5 = ½, 1.25 = 5/4, 0.3333… = 1/3 etc. Therefore, 0, 1, -2, 0.5, 1.25, 0.3333… etc. are some examples of rational numbers

Rational numbers include all the integers on a number line along with the fractions between integers. Look at the number line given below.

The set of rational numbers is denoted by Q.

Q = {… -1, …, -¾, …, -½, …, -¼, …, 0, …, ¼, …, ½, …, ¾, …, 1, …}

__Note__**: **

- There
are infinitely many rational numbers between any two integers.

- There
are infinitely many rational numbers between any two rational numbers.
