One third of a quart of paint covers one fourth of a basketball court. How much paint does it take to paint the entire basketball court?
one and one-third quarts

Standard: 7.RP.A.1
Domain: Ratios & Proportional Relationships
Theme: Analyze proportional relationships and use them to solve real-world and mathematical problems
Description: Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction (1/2)/(1/4) miles per hour, equivalently 2 miles per hour.
John eats a bowl of cereal for 3 of his 4 meals each day. He finishes two gallons of milk in eight days. How much milk does John use for one bowl of cereal? (Assume he only uses the milk for his cereal.)
One-twelfth of a gallon of milk
One cup of milk
Two cups of milk
One-sixth of a gallon of milk
