Rational numbers are those numbers that are integers and can be expressed in the form of x/y like 1/1
where both numerator and denominator are integers.
Irrational numbers are those numbers which cannot be expressed in a fraction.
An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point.
