Irrationals differ from Rationals by definition. If a real number is not a Rational Number then it is Irrational.
One way to find out if a number is either Rational or Irrational is to look at its decimal value. If the digits past the decimal point terminate then it is a Rational number. If the digits past the decimal point repeat the same digit forever, of if it repeats a sequence of digits over and over, then it is a Rational Number.
If the digits past the decimal point do not repeat in any pattern, and do not stop, then it is an Irrational number.
Another way to find out if a number is Rational or Irrational is if it can be exactly described by a fraction (ratio). If it is the same as some fraction, then it is a Rational Number. Irrationals cannot be exactly described as a fraction.
