1) Given that there are 24 students, we can write:
students
24 ---------------------- 100%
9 ------------------------------- x
2) Then we can solve this by setting a proportion:
Cross multiplying those rations, using the 1st Proportion property
students percentage
24 ---------------------- 100%
9 ------------------------------- x
24x = 900 Divide both sides by 24
x =37.5
So we can state that only 37.5% of that class finished their Homework
