# In Mr. Prime's class, 6/10 of the students had done their homework. Of these 2/3 had all correct answers. What fraction of the whole class had all correct answers?

$\frac{4}{10}$
If $\frac{6}{10}$, or 60% of the students did their homework, then you need to take that percentage and multiply it by $\frac{2}{3}$ to find the percentage of people who completed their homework and had all correct answers.
$\left(\frac{6}{10}\right) \left(\frac{2}{3}\right) = \frac{4}{10}$
