# Is 0 a Rational Number or Irrational Number?

TopToday we will check if ‘0’ is a rational number or an irrational number. If we recall the definition of Rational Numbers, they are the numbers which can be expressed in form of p/q where p & q both are integers and q ≠ 0. Moreover, we know 0 can be written as 0/1, we observe that both 0 & 1 are integers and the denominator i.e. ‘1’ ≠ 0. So we conclude that ‘0’ is a rational number and not irrational. We conclude that all whole numbers, all Positive and Negative Numbers are rational numbers.
