We know that,
A rational number is a number that is of the form of $\frac{p}{q}$, where $p$ and $q$ are integers and $q\ne 0$ . Also $p$ is called the numerator and $q$ is called the denominator.
Given fraction is $-7=\frac{-7}{1}$
Where, $p=-7$ and $q=1$
$\therefore q=1$ is denominator.

Hence, denominator of the given fraction is $1$.
