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 4/7 as many workers as the day crew, what fraction of all the boxes loaded by the two crews did the day crew load? Choose the correct choice:
A) 7/10  B) 2/5  C) 3/5  D) 4/5  E) 5/8
Method: X = No. of boxes loaded by day crew.   Boxes by night crew = 3/4 * 4/7 X = 3/7 X   % loaded by day crew = X/(X + 3/7X) = 7/10   7/10nswer 7/10
