Question

A teacher took a survey and found that 16 of 25 students liked a certain snack item best. Make a prediction of how many students liked the snack item best if there are 225 students.

Answer 1

For this case we first look for the percentage of students who liked the snack.
We have then:
(16/25) * (100) = 64%
Then, for 225 students we have:
(0.64) * (225) = 144
Answer:
144 of 225 students liked a certain snack item best
