一道数学题，不理解英文意思，请教。

sonnetsue

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。

Fraction ==〉碎片/一部分，貌似基本上应该是比一小吧？

anthonygong

The day crew load what fraction of all the boxes loaded by the two crews ？
这样是不是清楚点？

我的理解是，求白天装的货占总装货量的比例。

就是楼上这个意思~

这貌似是个倒装句，改为正常语序为what fraction did the day crew load of all the boxes loaded by the two crews ?
