To be able to answer this item, we are to convert the price units to a unit that has the same units of measure for the volume. For the purpose of unity, we use gallon as our basis.

For Gasoline:

Gasoline : $1.94 / gal

For Soda:

Use the conversion factor, 1 gallon = 3.79 L

Price = ($1.64 / L) x (3.79 L / gal) = $6.22/gal

For Milk:

Use the conversion factor, 1 gallon = 4 quarts

Price = ($0.89/qt) (4 qt / gallon) = $3.56/gallon

The least expensive of the items is the gasoline.
