3.75 cups

Step-by-step explanation:

Given that :

5 cups of liquid lemonade concentrate is mixed with 2.5 cups of water to make lemonade

5 cups of lemonade = 2.5 cups of water

Ratio :

5 / 2.5

For 2.5 cups of lemonade :

5 / 2.5 = 0.5

Multiply :

5 / 2.5 * 0.5 / 0.5

2.5 / 1.25

Hence, 2.5 cups + 1.25 cups = 3.75 cups of lemonade will be made with 2.5 cups of liquid lemonade concentrate
