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?
6 to 1
3 to 2
2 to 3
1 to 5
1 to 6
twice as many English majors as history majors的意思是:选英语的人是历史的两倍,也就是E=2H
同样选英语的是数学的3倍 E=3M
因此,H/M=3/2
选B
