assistant
How many hours is 3/8ths of a day? ** There are 24 hours in a day so 3/8ths of a day is (3/8)*24 = <<3/8*24=9>>9 hours
How many days are in 3 weeks? ** One week has 7 days so 3 weeks have 7*3 = <<7*3=21>>21 days
How many hours did each painter put in? ** Each painter put in 9*21 = <<9*21=189>>189 hours of work
