The question is to find the percentage of student who passed, after almost one hour going back and forth with this, I cannot foresee the solution arriving anytime soon… can someone please explain?

**Editor**

total_students = int(input(“How many students are in the class?”))

passing_students = int(input(“How many students passed this test?”))

def find_percentage():

percentage = passing_students / total_students

percentage = int(find_percentage() * 100)

print("The percentage of students who passed is " + str(percentage) + “%”)

**Shell**

How many students are in the class?36

How many students passed this test?9
