To find out how many students need help, we first calculate \( \frac{1}{4} \) of the total 60 students:
\[ \frac{1}{4} \times 60 = 15 \]
So, 15 students need help. If Mr. Brokaw divides these 15 students into 5 small groups, we can find the number of students in each group by dividing the total number of students needing help by the number of groups:
\[ \frac{15}{5} = 3 \]
Thus, there are 3 students in each group.
