Question

Please help! On a field trip, there are 3 chaperones for every 20 students. There are 92 people on the trip.

Part a: How many chaperones are there?
Part b: how many students are there?

Answer 1

A: 12 B: 80

Explanation:

92 - 80 = 12

80 students

12 Chaperones

Answer 2

12 chaperones and 80 students

Explanation:

Start by multiplying the numbers seperatly and then add. Keep doing this till you get to 92.

20(2)=40. 3(2)=6 46

20(3)=60. 3(3)=9 69

20(4)=80. 3(4)=12 92

Now you know there are 12 chaperones and 80 students. There are other ways to answer this problem like using systems of equations but it still gives the correct answer and is less advanced.

Hope this helps:)
