Question

If you made 12 pies and each one has 1 cup of sugar how many cups will you need to make 27 pies

Answer 1

15 cups, I am pretty sure, i might be under thinking it

Answer 2

If each pie has 1 cup of sugar, then you need 12 cups of sugar to make 12 pies. So, if there are 27 pies and 27 cups of sugar, then you subtract 12 from 27.

Work: 
27-12 = 15

Final Answer: 15 cups of sugar
