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.

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

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
is he right?
Of course, he's right. He's one of our math and science tutors here.
