Answer
7
Work Step by Step
To round a mixed number to the nearest whole number we must determine whether the fraction is less than $\frac{1}{2}$. If the fraction is less than one half, the whole number does not change and the fraction is dropped.
$\frac{1}{2}=\frac{4}{8}$
$\frac{1}{8}\lt\frac{4}{8}$, so $\frac{1}{8}\lt\frac{1}{2}$
Since $\frac{1}{8}$ is less than $\frac{1}{2}$, $7\frac{1}{8}$ rounds to 7.
