If one quart of paint is exactly enough for two coats of paint on a 9-foot by 10-foot wall, how many quarts of paint are needed to apply one coat of paint to a 10-foot by 12-foot wall?  Express your answer as a common fraction.

1 qrt covers TWO x 9 x 10 = 180 sq ft

 

10ft x 12 ft   x 1qt/180ft^2 = 120/180 qt = 2/3 qt
