Feedback: Not quite! Divide the central angle for Studying by 360°: $60 \div 360 = \frac{1}{6}$. Multiply by 24 hours: $ \frac{1}{6} \times 24 = 4$ hours.

Feedback: Not quite! Divide the central angle for Basketball by 360°: $90 \div 360 = \frac{1}{4}$. Since $\frac{1}{4}$ corresponds to 60 students, the total number of students is $60 \div \frac{1}{4} = 240$. For Volleyball, its central angle is $120°$, which is $\frac{1}{3}$ of the total. Multiply the total students by $\frac{1}{3}$: $240 \times \frac{1}{3} = 80$.
