Question

3. Han and Tyler are following a polenta recipe that uses 5 cups of water for every 2

cups of cornmeal.
• Han says, "I am using 3 cups of water. I will need 1 1
- cups of cornmeal."
o Tyler says,"I am using 3 cups of cornmeal. I will need 7> cups of water."
Do you agree with either of them? Explain your reasoning.

Answer 1

You definitely don’t want to agree with Tyler, although Han is closer. If you do 5/2 you get 2.5. Therefore every cup is worth 2.5. Since you have 3 cups, you will do 3 • 2.5, which equals 7.5. 7.5 should be the exact answer, therefore neither Han or Tyler are correct.
