Final answer:
To make 3 liters of Vanika Milkshake, you would need 0.75 liters of milk and 3 liters of flavoring.
Step-by-step explanation:
To make Vanika Milkshake, the ratio of milk to flavoring is 1:4. This means that for every 1 part of milk, you need 4 parts of flavoring. To find out how much milk and flavoring are needed to make 3 liters of milkshake, you can set up a proportion.
Let's assume the amount of milk needed is x liters. According to the ratio, the amount of flavoring needed would be 4x liters. Now, we can set up the proportion:
x/4x = 3/1
Simplifying the proportion, we get x = 0.75 liters. Therefore, you would need 0.75 liters of milk and 4x0.75 = 3 liters of flavoring to make 3 liters of Vanika Milkshake.
