Question 12

A school survey found that 18 out of 30 students prefer pizza to hamburgers. If the school has 400
students, which is the best prediction of the total number of students who prefer pizza? (Hint: Write and
solve a proportion.)

Answer 1

240

Explanation

18/30 = 9/15

9/15 = 3/5

3/5 = 0.6

0.6 x 400 = 240

Ergo it is likely 240 students would choose pizza
