To determine how many fifths of liquor equal a half gallon, we need to understand the relationship between fifths and gallons.
A fifth of liquor is a common bottle
size that contains 750 milliliters (mL) of liquid.
To find out how many fifths are in a half gallon, we can divide the volume of a half gallon by the volume of a fifth:
1920 mL (half gallon) / 750 mL (per fifth) = 2.56 fifths
Therefore, a half gallon is equivalent to approximately 2.56 fifths of liquor.
