Final answer:
The pancake recipe that calls for 2 1/2 cups of milk requires 600 milliliters of milk, since one cup is equivalent to 240 milliliters.
Step-by-step explanation:
The pancake recipe requires 2 1/2 cups of milk. To find out how much this is in milliliters (ml), we can use the given conversion: 1 cup of milk is equivalent to 240 milliliters. To calculate the total amount of milk in milliliters, we need to multiply the number of cups by the conversion factor.
Here's the calculation:
2 1/2 cups × 240 milliliters/cup = 600 milliliters.
Therefore, the recipe calls for 600 milliliters of milk.
