Answer
$-11,\displaystyle \ -\frac{3}{7},\ 0,\ 0.45,\ \sqrt{25}$
Work Step by Step
Rational numbers are numbers that can be written as $\displaystyle \frac{a}{b}$,
where a is an integer, and b is a positive integer.
$-11=\displaystyle \frac{-11}{1}$, a rational number
$\displaystyle -\frac{3}{7}=\frac{-3}{7}$, a rational number
$0=\displaystyle \frac{0}{1}$, a rational number
$0.45= \displaystyle \frac{45}{100}$, a rational number
$\sqrt{23}= $... , not a rational number
$\displaystyle \sqrt{25}=5=\frac{5}{1}$, a rational number
