I need an explanation on how to work this out

Answer:
make 360×each number given/15 students to start drawing
360×7/15=168°
360×5/15=120°
360×2/15=48°
360×1/15=24°
now draw each one from the radius give to the clockwise
if you don't know what's clockwise direction, see it from your house or tell anybody in your home to tell you where is clockwise
after you finish drawing, label each section by writing the names on the correct sections ( you can write in or out of the circle)
