2. 8; There are 2 pints per quart, so for 4 quarts there would be 8 pints
3. 24; Since there are 8 fluid ounces in each cup, there are 24 fluid ounces in 3 cups.
5. 11; There are 2 cups in each pint, so 5.5 pints would equal 11 cups.
6. 24; Since there are 4 quarts in each gallon, then 6 x 4 = 24, so 24 quarts.
Hope that helps!
