Answer
$-7,-\frac{4}{5},0,0.25,\sqrt 4,\frac{22}{7}$
Work Step by Step
Rational numbers are real and can be repeated as $\frac{p}{q}$. $\sqrt 3$ and $\pi$ continue for a long time without repeating, so they are not rational. The rest of the numbers are.
$\{-7,-\frac{4}{5},0,0.25,\sqrt 3,\sqrt 4,\frac{22}{7},\pi\}$
$-7,-\frac{4}{5},0,0.25,\sqrt 4,\frac{22}{7}$
