Answer: 18
Explanation:
The ratio of small to medium lemonades is 3 to 2. The ratio of medium to large lemonades is 3 to 2. Multiply 3/2 by 3/2 and you get 9/4. 9/4 is the amount of small lemonades needed for ONE large serving. Since you need the answer for EIGHT large servings, multiply 9/4 by 8 and you get 18, which is your answer.
