# What is the set of numbers to which -5/12 belong?

Rational numbers are those numbers which can be written as $\frac{p}{q}$, where $p$ and $q$ are integers and $q \ne 0$.
As, $- \frac{5}{12}$ belongs to the set of rational numbers, as it is a ratio of two integers $- 5$ and $12$, of which latter is not zero.
