aftr loading a dock each workwr on nyt crew loaded 3/4 as many boxes as worker on day crew if nyt crew has 4/5 as many worker as day crew what fraction of all all d boxes loaded by two crews did the day crew load.

• If workers in day crew are 20 & night crew are 16
  and each worker in day crew loads 4 boxes and worker in night crew loads 3 boxes, then
  Total boxes loaded = 20*4+16*3= 128
  Boxes loaded by day crew = 20*4=80
  fraction of boxes loaded by day crew to total boxes loaded = 80/128 = 5/8
