Answer:
if you use 5 cups of sugar in the recipe, you would need 15 cups of flour.
Explanation:
If 1 cup of sugar is used for every 3 cups of flour in a recipe, we can use the given ratio to determine the amount of flour needed when using 5 cups of sugar.
The ratio is 1 cup of sugar to 3 cups of flour. To find the amount of flour needed, we can set up a proportion:
1 cup of sugar / 3 cups of flour = 5 cups of sugar / x cups of flour.
Cross-multiplying the proportions:
1 * x = 3 * 5,
x = 15.
