At a certain college there are twice as many English majors as history majors and three times as many English majors as mathematics majors. What is the ratio of the number of history majors to the number of mathematics majors?
(A) 6 to 1
(B) 3 to 2
(C) 2 to 3
(D) 1 to 5
(E) 1 to 6
多简单啊,但为什么答案是B而不是C. 请问“the ratio of A to B"难道不是A/B吗？
