Rational numbers are numbers that can be expressed as a fraction of two integers. In the set B, $18, -10, 0, \frac{2}{3}, \sqrt{16},$ and $0.61$ are rational. $\sqrt{16}$ is rational because it equals 4, a whole number. $\sqrt{5}$ is not rational because it cannot be expressed as a fraction of two integers.
