Consider the recipe for making tomato and garlic pasta. 2 cups noodles + 12 tomatoes + 3 cloves garlic → 4 servings pasta if you have 7 cups of noodles, 27 tomatoes, and 9 cloves of garlic, how many servings of pasta can you make? which ingredient limits the amount of pasta that it is possible to make?

You can make with

7 Noodles: 14 Servings pasta;  

27 Tomatoes: 9 Servings pasta;

9 Cloves of Garlic: 12 Serving Pasta;  

Explanation:

Noodles 7 ÷ 2 = 3,5 x 4 = 14  

Tomatoes 27÷12 = 2,25 x 4 = 9

Garlic 9 ÷ 3 = 3 x 4 = 12

The ingredient that limits the amount of tomato and garlic pasta is the noodles. The other ingredients can be used in less quantity and still result in the same amount of pasta. It would change the flavor but not the amount of pasta.    

where is the rest of the question. this isn't making sense. can you upload a picture of the question?
