Step-by-step explanation:
Since there aren’t going to be fractions of people, you can just count up using the whole numbers in the ratio (4 on the left, 7 on the right) and then check if the sum is between 24 and 40.

8:14 = 22 students (not enough)
12:21 = 33 students (fits criteria)
12 boys, 21 girls, for a total of 33 students.
