Answer:
Servings: 3, 6, 9, 12
Soup: 5, 10, 15, 20
Explanation:
The given ratio is 12:20. We can use this ratio to find the rest.
Simplify the ratio to 6:10 and 3:5. That gives us the unknown values for the first two. We can see that for every 3 servings, there are 5 soups. That should help you get the answer.
