Total hours worked in 4 weeks = (363/8) + (411/4) + (401/2) + (383/8)
                                                 = (363 + 822 + 1604 + 383)/8
                                                 = 3172/8 hours
                                                 = 793/2
Then
Average hours worked in a 4 weeks = (793/2) hours
So
Average hours worked in 1 week = 793/(2 * 4) hours
                                                     = 793/8 hours
So the average number of hours worked in 1 week is 793/8 hours.
