Answer 2

Rational Numbers :

Any number of the form p/q, where p and q are both integers with q ≠ 0 is called a Rational Number.

In set builder form, the set of Rational Numbers can be written as

  ℚ = {x : x = p/q, p, q ∈ ℤ, q ≠ 0}

Answer :

Yes, 0 (zero) is a Rational Number because 0 can be expressed as 0/1, 0/2, 0/3, 0/4, ... where the numerator is always 0 and the denominator is any non-zero integer.
