Mr. Frost is painting his garage, which has a surface area of 500 square feet. He has 1 3/4 gallons of paint. If one gallon of paint covers 150 square feet, how much more paint must Mr. Frost buy? Show your work. Please help.

  • Math -

    500 / 150 = 3 1/3 gallons

    3 1/3 - 1 3/4 =
    3 4/12 - 1 9/12 =
    2 16/12 - 1 9/12 = 1 7/12 gallons

  • Math -

    500 ft^2 * 1 gal/150 ft^2 = 3 1/3 gallons needed

    3 1/3 - 1 3/4 = 2 16/12 - 1 9/12

    = 1 7/12
