Ответ:
she will sew have sewn five dresses and be 1/3 done with the sixth one in an hour.
step-by-step explanation:
3/4 of an hour=45 mins
lucy makes 1 dress per 11.25 minutes
45 mins+11.25 mins=56.25 mins
60 mins- 56.25 mins=3.75 mins
3.75 mins is 1/3 of of 11.25 mins
therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
