Rational number:
Rational numbers are the numbers that can be expressed in the form of a ratio (PQandQ0)
and also if decimal number represents the number after the decimal is repeating, then it is a rational number.
Irrational numbers:
It is impossible to express irrational numbers as fractions or in a ratio of two integers, irrational numbers have endless non-repeating digits after the decimal point.
34 It is a rational number.
9=3 It is a rational number.
33=3 It can not be simplified more, so, it is a irrational number.
255=5 It can not be simplified more, so, it is a irrational number.
20=201 it is a rational number.
1.11222 it is a rational number because 2 is repeating here.
5.5015132 it is non-recurring and non-terminating. So, it is a irrational number.
626262 it is a rational number.
