A recipe for brownies requires 2 1/3 cups of flour. If a person wanted to make 9 times that amount for a bake sale how much flour would he need
To find out how much flour is needed to make 9 times the recipe, you can start by determining the amount of flour required for one batch of brownies, and then multiply that by 9.
The given recipe requires 2 1/3 cups of flour. To simplify the calculation, let's convert this mixed number into an improper fraction: 2 1/3 = (2 × 3 + 1) / 3 = 7/3.
So, the amount of flour required for one batch of brownies is 7/3 cups.
To find out how much flour is needed for 9 times the recipe, multiply 7/3 by 9:
(7/3) × 9 = (7 × 9) / 3 = 63/3 = 21 cups
Therefore, to make 9 times the amount of the given recipe, you would need 21 cups of flour.
