Question

a middle school wants to have a student-to-teacher ratio of 25:2 .if the school has 325 students,how many teachers does it need

Answer 1

26 teachers

Explanation:

First, set up a proportion.

`(25)/(2)` =
`(325)/(x)`

Then cross-multiply to get your equation.

25 * x = 325 * 2

25x = 650

Finally, isolate the variable to find your answer.

x = 650/25

x = 26 teachers

Answer 2

the school needs 26 teachers
