# Rational And Irrational Numbers Definition

A number that is made of simple fraction is defined as Rational number. The numbers that we use in rational number must be integers only.
Like if we have p, q as integers. Then Rational Numbers can be expressed as $\frac{p}{q}$ where denominator q can’t be zero. Rational numbers are non-unique that is a rational number as a fraction is not unique.
For example: 0.35 and 12.256 both are rational numbers. A number let 0.500 can also be represented as $\frac{500}{1000}$

The other type of number that moves parallel to Rational number is defined as Irrational Numbers. In terms of mathematics Irrational numbers are those numbers that cannot be represented as a Ratio of two numbers. We can also say that all numbers that are not rational are irrational numbers. An irrational has endless non-repeating digits that appear after the decimal Point.
For example:  $\pi$ = 3.141592, $\sqrt{2}$ = 1.414213, in this both examples have endless non-repeating digits that appears after the decimal point.
