58.33% (58% when rounded)
Explanation: First, you want to find the totale amount of students!
14 + 2 + 3 + 5 = 24 students
Then just look at the number of students who did the homework and pass, which is 14.
Then divide the students who did the homework and pass over all of the students (multiply by 100 to get a percent): 14 / 24 • 100 = 58.33% (58% when rounded)
