Which number can be written in the form \(\frac{p}{q}\), where (p) and (q) are integers and (q\ne0)?

Correct answer: \(0.\overline{37}\)

\(0.\overline{37}=0.373737\ldots\) is a recurring decimal, so it is a rational number. It can be written as \(\frac{37}{99}\), where both numerator and denominator are integers and the denominator is non-zero. In contrast, \(\sqrt{11}\) and \(\sqrt{13}\) are square roots of non-perfect squares and are irrational; \(\pi\) is also irrational. Exam tip: every terminating or recurring decimal is rational.
