Take Perry's sauce for your family party:

5 cups Swiss and 7 cups cheddar.

Multiply both amounts by 3:

15 cups Swiss and 21 cups cheddar.

The cafeteria recipe is 15 cups Swiss and 17 cups cheddar, so

15 cups Swiss and 21 cups cheddar are an incorrect ratio.

Answer: No

No. Perry is using an incorrect ratio.

You have to cross multiply and when you do that you get 105 and 85 so the ratios are not the same.

Hope this helps!

Have an amazing day :)
