The ratio of flour to sugar for the banana bread recipe is 5 to 2. If 3 cups of sugar are used, then how many cups of flour are needed?

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.

7.5 cups need flour that's your answer
