-11, -$\frac{3}{7}$, 0, 0.45, $\sqrt {25}$

#### Work Step by Step

-11 is a rational number because it is an integer. -$\frac{3}{7}$ is a rational number because it is a fraction. 0 is a rational number because it is whole number. 0.045 is a rational number because it is a terminating decimal. $\sqrt {25}$ is a rational number because it is equivalent to 5 which is a natural number. $\sqrt {23}$ is not on the list of rational numbers because it results in a never ending decimal that cannot be written as a fraction so it is irrational.
