# Definition of Rational Number

Rational Numbers are numbers that are expressed as a Ratio of two integers. Rational numbers are terminating or recurring decimal numbers written in the form of fraction $\frac{a}{b}$ in which 'a' and 'b' are integers and the denominator 'b' not equal to zero.

e.g,
$\frac{1}{2}$ is a rational number.

0.25 is a rational number ($\frac{1}{4}$).

3 is a rational number ($\frac{3}{1}$).

2.32 is a rational number ($\frac{232}{100}$).

-6.8 is a rational number (-$\frac{68}{10}$).

The following are some of the properties of Rational Numbers:

1. The addition, subtraction, multiplication and division of two rational number is also a rational number.
2. Rational numbers holds true for commutative and associative law of addition and multiplication.
3. Between two rational numbers there are infinite number of other rational numbers.
4. Rational numbers can be both positive and negative.
