Sally paints a house in 4 hours Sam paints it in 6 hours how many hours will it take both to paint the house

• Sally's 1 hr work = 1/4
  Sam's 1 hr work = 1/6
  
  Sally and sam's 1 hr work = 1/4 + 1/6
  ---------------------------> 10/24 = 5/12
  
  So they ll finish d work in 12/5 hrs (ie) 2 2/5 hrs
  
  (ie) 2 hrs 24 mins
