Question

The GED preparation class has a teacher to student ratio of 1:12. If there are 36 students in the class, how many teachers are present?​

Answer 1

3

Explanation:

Step 1: Recognize you can put 1:12 into a fraction along with 36 students with 'x' as number of teachers when you have 36 students

`(1)/(12)`

`(x)/(36)`

Step 2: Set the 2 fraction equal to each other

`(1)/(12) =(x)/(36)`

Step 3: Cross multiple and solve for 'x'

`12x=36\\x=3`

Therefore there are 3 teachers present when there are 36 students in the class
