The fourth graders are painting one of the school walls. They started with 3 3/4 gallons of paint, but it wasn't enough, so one of the parents brought them another 2 1/4 gallons of paint. How much did they have in all?
In the end it took 5 1/4 gallons of paint to cover the wall. Did they have any paint left over? If so, how much?
3 3/4 + 2 1/4 = 5 4/4 = 6 gallons of paint in all
