Sarah has 12 apples. She gives 2 to Ellie, 3 to Steve, and 1 to Rod. How many apples does Sarah have left?
Justin, Patrick, and Sean can finish painting the fence in 3 hours. If Justin does the job alone she can finish it in 6 hours. If Patrick does the job alone he can finish it in 9 hours. How long will it take for Sean to finish the job alone?
All together= 1/3, Justin= 1/6, Patrick= 1/9 Sean=1/x 1/3=1/6+1/9+1/x multiply all numerators by 36x 36x/3=36x/6+36x/9+36x/x 12x=6x+4x+36 2x=36 x=18 It will take Sean 18 hrs to do it alone
