Ateacher 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.

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
 
 144 of 225 students liked a certain snack item best

The answer is 225 miles per 4.5 hours. hope this ; )
