Answer:
7.5 cups of flour are needed
Step-by-step explanation:
To figure out how much flour you need for each cup of sugar, you can divide both 5 and 2 by 2. You will get that 2.5 cups of flour are needed for each cup of sugar. Since you have 3 cups of sugar, you multiply 2.5 by 3. 2.5 x 3 is 7.5, so the answer is 7.5 cups of flour.
