On a field trip there are 3 chaperones for every 20 students. there are 92 people on the trip. how many chaperones are there?

Add the chaperones to students: 3 +20 = 23

Divide total people by that:

92 / 23 = 4

Multiply that number by the number of chaperones in the ratio:

4 x 3 = 12

There are 12 total chaperones.

Number of chaperones on the trip were 12.

Step-by-step explanation:

Let there were x students on  the trip.

Number of chaperones on 20 students = 3

Therefore, number chaperones required for x students =

Total number persons = Number of students + Number of chaperones

                                     = x +

                                     =

Since number of persons on the trip has been given as 92.

92 =

x =

 = 80

Therefore, number of students on the trip are 80.

And number of chaperones on the trip = 92 - 80 = 12
