A science museum requires 3 adult chaperones for every 15 students on a field trip. How many chaperones would be needed for a group of 125 students?
Answered by Ms. Sue
15/3 = 1 chaperone for every 5 students.

125/5 = ? total chaperones



Answered by Kayla
1) There are 3 adults per 15 students, so you can make a ratio 3adults/15students.
2) Next, set up the second ratio and combine where 3adults/15students = X/125students. X is the number of adults needed.
3) Arrange the equation by cross muliplying and you get 375 = 15X
4) X= 25 adults

15/125 = 8.333 groups of 15 students

8.33 x 3 (chaperons) = 24.99 rounded 25
