At george washington high school, the ratio of graduating seniors that go on to college compared to those who do not is 7 : 4. last year, 28 students did not go on to college. how many students did?

Hi, thank you for posting your question here at .

This problem can be solved easily by applying ratio and proportion. In this case, the ratio between those who go to college and those who do not is 7/4. Then, when there are 28 students, you can determine the number of which who don't go to college by using the 7/4 ratio value

7/4 = 28/x
x = 16

Thus, 16 students did not go on to college.
