Using a number line, what whole number and rational number to the nearest half is 30−−√ between?(1 point)

To find the whole number and rational number nearest to $\sqrt{30},$ we need to find the whole number and rational number that is closest to $\sqrt{30}.$ We note that $\sqrt{30}$ is between $\sqrt{25} = 5$ and $\sqrt{36} = 6,$ so the whole number nearest to $\sqrt{30}$ is $\boxed{5}.$

To find the rational number nearest to $\sqrt{30},$ we need to find the rational number that is closest to $\sqrt{30}.$ We observe that $\sqrt{30}$ is closer to $5$ than to $6,$ so the rational number nearest to $\sqrt{30}$ is $5.$
