Answer: they will taste the same.
Explanation:
"9 Tomatoes for every 12 cups of soup" is what they said. Then they said "Today they made 8 cups of soup with 6 tomatoes." There is a 3 number difference in all of the number of you line them up. So if you add three tomatoes to Today's soup and 3 more cups of soup to today's recipe. You would get 9:12 which is what we are looking for. The same tomato soup as usual. No changes at all. So the answer is They will tast the same.
