1) Irrational numbers: The number which can't expressed in the form of [tex]\frac{p}{q}[/tex] are called irrational numbers. For example [tex]\sqrt{2} , \sqrt{3}[/tex] and [tex]-\sqrt{5}[/tex] etc.
2) Rational numbers: The number which can be expressed in the form of [tex]\frac{p}{q}[/tex] are called irrational numbers. For example [tex]\frac{4}{7} , 3.4[/tex] and -5.2 etc. It is categorized in two parts fractional and integer numbers.
(i) Fractional numbers: The numbers which are not a complete number and the number in decimals, fraction are called fractional numbers. For example -3.6, [tex]\frac{7}{2}[/tex] and 6.1 etc.
(ii)Integer numbers: The complete number which has no decimal value is called integer numbers. For example-8,-2, 0, 5,7 and 100 etc.
If a number is not integer, it means it can be in fraction form and in the form of root.
