Answer: Don't use this if you are taking a test, please!
Step-by-step explanation:
Hello! This is actually easier than you think! All you have to do is make what is already written as a proportion. You don't have to solve anything! You are already given one number which represents the first thing you were told, 4 cups of rice. For 4 cups of rice, 5 cups of water are needed. As a proportion, you would write 4/5. For the second proportion you would write the 16 cups of rice per 20 cups of water as 16/20. The answer is 4/5 = 16/20. Hope this helps with your homework!
