At a loading dock, each worker on the night crew loaded 3/4 as many boxes as each worker on the day crew. If the night crew has 4/5 as many workers as the day crew, what fraction of all the boxes loaded by the two crews did the day crew load?
(A)
1/2
(B)
2/5
(C)
3/5
(D)
4/5
(E)
5/8
这道题其实也不是很难,我只是对最后一句话,不太理解。 问的是合起来load的货,和白天load的比。
答案是E, 但是我觉得是8/5啊。 5/8是白天load的比上合起来的吧。 反正我对最后一句话理解的不是很好,请大家帮忙解释一下,谢谢。作者: anthonygong 时间: 2013-6-24 06:16
