conversations.value: Mr. Willson worked on making his furniture for 3/4 an hour on Monday. On Tuesday, he worked for half an hour. Then he worked for 2/3 an hour on Wednesday and 5/6 of an hour on Thursday. If he worked for 75 minutes on Friday, how many hours in all did he work from Monday to Friday?

conversations.value: Since there are 60 minutes in an hour, then Mr. Willson worked for 60 minutes x 3/4 = 45 minutes on Monday.
  He worked for 60 minutes/2 = 30 minutes on Tuesday.
  He worked for 60 minutes x 2/3 = 40 minutes on Wednesday.
  He worked for 60 minutes x 5/6 = 50 minutes on Thursday.
  So Mr. Willson worked for 45 + 30 + 40 + 50 + 75 = 240 minutes.
  In hours, it is equal to 240/60 = 4 hours.
