On a school field trip, the school requires that there are 3 teachers for every 75 students. If 125 students attend the trip how many teachers are needed? Write and solve a proportion.

Question

Pls help me i don't know how to solve it

Answer 1

3 for 75 is one for every 25
so
125 students (1 teacher/25 students) = 5 teachers
or just skip the thinking and write
125 students (3 teachers/75 students) = 5 teachers
The point is write it so students cancel top and bottom and you are left with teachers

Answer 2
