how many fifths in a half gallon

[OEmiliano]

Hello there! Great question. According to the provided information, there are exactly 2.5 fifths in a half gallon.

To understand how we get that number, it helps to look at the fluid ounces. A half gallon is equal to 64 fluid ounces. A "fifth" of liquor is an old measurement that equals 25.6 fluid ounces.

So, if you divide the 64 fluid ounces in a half gallon by the 25.6 fluid ounces in a fifth, you get 2.5. This means you would need two and a half fifths to make up a half gallon.
