A recipe Mia is making calls for 8 cups of milk. She has 2 liters of milk. Her mother says she has enough milk. Is her mother​ correct? Explain.

• Yes. There are 8 cups in 2 quarts and 2 quarts≈1.9 liters.​ So, there should be about 0.1 liter of milk left over.

• No. There are 6 cups in 2 quarts and 2 quarts≈1.2 liters.​ So, there​ isn't enough milk to make the recipe.
