this school has the same number of freshman and sophomores 
the number of juniors is 2/3 of the number of sophomores

now can you write the number of sophomores and juniors?

anonymous · Answer

so would it be (2/3)x

tamtoan · Answer

correct, that's the number of juniors ...sophomores and freshman are the same...so they both would be x ....now 

the number of seniors is 3/4 of the number if juniors  (i believe the word IF should be OF, may typo)...can you write the number of seniors?

tamtoan · Answer

may = maybe

anonymous · Answer

(3/4)x I think

tamtoan · Answer

it's 3/4 of the number of juniors ...so it's not (3/4)x ...it's 3/4 of (2/3)x.....so it should be 
(3/4).(2/3)x = ? 
then add all the students to get the total, you have a linear equation with one variable, can be solved, try that and if you have any problem, let me know, i'll help again
