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 an identical recipe that serves 18 people? Explain your reasoning.

Answer 1

Well 18 people is 3/4 of 24 people. So for each ingredient just multiply the value by 0.75.

3 litres of lemon line Soda
1.5 pints of sherbet
4.5 cups of ice
