How many cups of berries in a quarter pound?

A quarter pound is equal to 0.25 pounds. There are 16 ounces in a pound, so 0.25 pounds is 16 ounces * 0.25 = 4 ounces. There are 8 fluid ounces in a cup, so 4 ounces is 4 ounces * (1/8) cup/ounce = 0.5 cups. Since berries are typically sold in cups, you can say there is 0.5 cups of berries in a quarter pound.
