The number of students in the two classes A and B is equal, and some students in each class take the mathematics elective course. The number of students in class A who take the mathematics elective course is exactly the number (1/3) of the number of students who do not participate in class B. The number of students in class B who take the mathematics elective course Exactly (1/4) of the number of people who did not participate in Class A. So what percentage of the number of people in class A who did not participate is the number of people in class B who did not participate?
甲、乙两班的学生人数相等，各有一些学生参加数学选修课，甲班参加数学选修课的人数恰好是乙班没有参加的人数的(1/3)，乙班参加数学选修课的人数恰好是甲班没有参加的人数的(1/4)．那么甲班没有参加的人数是乙班没有参加的人数的几分之几？
