You can put this solution on YOUR website!
freshmen%3Ajunior=3%3A4 or
freshmen%2Fjunior=3%2F4...eq.1 => 4freshmen=3junior => +freshmen=%283%2F4%29junior
junior%2Fsenior=7%2F6...eq.1 => junior=%287%2F6%29senior
so, freshmen=%28cross%283%291%2F4%29%287%2Fcross%286%292%29senior=%287%2F8%29senior...plug in eq.1
freshmen%2Fsenior=%287%2F8%29senior%2Fsenior => freshmen%2Fsenior=7%2F8
so, the ratio of the number of freshmen and the number of who attended to the game senior is 7%3A8
