1. The problem statement, all variables and given/known data 1/4 of all the juniors and 2/3 of all the seniors are going on a trip. If there are 2/3 as many juniors as seniors, what fraction of the students are not going on the trip? 2. Relevant equations Simple fraction based equations. 3. The attempt at a solution Not Going to Trip = 1/4Juniors(J) + 2/3Seniors(S) I am not able to solve it completely because I cant understand what is meant by "2/3 as many juniors as seniors". I think that J=2/3S. Some body please guide me. Zulfi.
