The ratio of adults to students on a class field trip is 2 to 5. If there are 12 more students than adults, which proportion and solution represent this situation

So, there are 3 more "parts" of students than of adults (5 - 2), right?

Those 3 parts are made up of 12 people.

12/3 = 4 people per part

2(4) = 8 adults

5(4) = 20 students
