* Four-fifths is a fraction, representing a part of a whole.
* Quarts are a unit of volume, typically used for liquids.
To make a conversion, you need to know what "four-fifths" *of* something is. For example:
* Four-fifths of a gallon: There are 4 quarts in a gallon, so four-fifths of a gallon would be (4/5) * 4 quarts = 3.2 quarts.
* Four-fifths of a cup: There are 4 cups in a quart, so four-fifths of a cup would be (4/5) * (1/4) quart = 0.2 quarts.
Please provide more context so I can help you calculate the correct number of quarts!
