See explanation
Step-by-step explanation:
Given that 9 cups of macaroni requires 27 cups of water
Therefore, 1 cup of macaroni will require 27/9 = 3 cups of water
Now i can help you to work out the correct way of filling the table;
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 9 cups of water
x = 9 *1/3
x = 3 cups of macaroni
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 33cups of water
x = 33 *1/3
x = 11 cups of macaroni
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 21 cups of water
x = 21 *1/3
x = 7 cups of macaroni
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 27 cups of water
x = 27 *1/3
x = 9 cups of macaroni
Use this to tick the table.
