Question

If the ratio of students with green shirts to total students in a class is 3 to 8, and are 12 students wearing green shirts, how many are there without green shirts?

Answer 1

The answer would be 20

Answer 2

20

Step-by-step explanation:

You would set up a proportion in order to solve this

3 green 12 green

------------ = ------------

8 total x total

Then you would cross mulitply for x and get 32. Since that is the total number, you would have to subract the 12 from 32 to get 20.
