To find the percent divide the number given for the respective category and over the whole number of students. For example for the students who chose sausage 18 you do this: 18 / 200 =0.09 Then you move the decimal two places to the right to get 9%

Do you get it?

Totals students = 200

Sausage = 18/200 (*100)  = 9/100 = 9%
Mushroom = 6/200 (*100) = 3/100 = 3%
Black Olive = 26/200 (*100) = 13/100 = 13%
