5.2 Real World Calculations: Step 15

Hey can someone help me out with program on step 15 of module 5.2.
So, I need to make a program that will find a percentage of students who pass a given test. The user must be able to enter the amount of students in the class & the amount that pass the test. I need to fill in the find_percentage function that will return the percentage into decimal form.
So, I understand how the calculation works but I am a little lost on how to input that into the program and what I need to put into the function.
I know I need a “return” but after that I am confused. Can someone please help me out!!
Thank you,

Never mind I figured it out!!!
