Yes, 0 is considered a rational number. A rational number is defined as any number that can be expressed as the quotient or fraction \( \frac{a}{b} \), where \( a \) is an integer and \( b \) is a non-zero integer. In the case of 0, it can be expressed as \( \frac{0}{1} \), \( \frac{0}{2} \), or any other fraction where the numerator is 0 and the denominator is a non-zero integer.
