10% is your answer. Take the total number of students and use that as a divisor of 100 so 100/20 = 5% so each kid represents 5 percent. Then if you take the 2 kids who got vanilla cup cakes and if each one is 5% then 5%+5%= 10%
Answer: 10% of students picked a vanilla cupcake.
Explanation: 18 + 2 = 20. 20 is 100% of 20. 20/10 = 2, and 2 is 10% of 20, therefore 10% of students picked a vanilla cupcake.
