<human>:  Greg puts clean sheets on 4 twin beds and 1 king size bed every week. His laundry machine will only allow him to wash 2 twin sets of sheets at a time and 1 king set of sheets at a time. How many loads of laundry does he do in a year?
<bot>: How many loads of twin size sheets does Greg have to wash each week? ** He has to wash 4 twin size sheet sets each week and the machine will only let him do 2 sets at a time so he has to do 4/2 = <<4/2=2>>2 loads of twin size sheets
How many loads of laundry does Greg do in a week? ** He does 2 loads of twin size sheets and 1 load for king size sheets every week for a total of 2+1 = <<2+1=3>>3 loads
How many loads of laundry does Greg do in a year? ** Over 52 weeks (1 year) he does 3 loads of laundry a week for a total of 52*3 = <<3*52=156>>156 loads of laundry
