To find out how many liters of milk are in each serving, you can divide the total volume of milk by the number of servings.
Given that the carton contains 1.92 liters of milk and there are 8 servings, the calculation would be:
\[ \text{Milk per serving} = \frac{\text{Total milk}}{\text{Number of servings}} = \frac{1.92 , \text{liters}}{8} \]
Calculating that:
\[ \text{Milk per serving} = 0.24 , \text{liters} \]
So, each serving contains 0.24 liters of milk.
