Question

A punch recipe that serves 24 people calls for 4 liters of lemon-lime soda, 2 pints of sherbet, and 6 cups of ice. How much of each ingredient would you need to make in identical recipe that serves 12 people?

Answer 1

For 12 people, the identical recipe that would serve this amount would be 2 liters of lemon-lime soda, 1 pints of sherbet, and 3 cups of ice.
To figure out the corresponding proportion from 24 servings to 12 servings, first we divide 24 by 12, which is 2. The number 2 represents how many times bigger the original recipe is to the smaller 12 servings version, which mean the 24 people version would be twice as big compared to the 12 people serving. So all we have to do to the recipe is divide it in half. And so 4 liters divided by 2 is 2 liters of lemon-lime soda, 2 pints of sherbet becomes 1 pint, and 6 ice cups turns into 3 cups of ice.
