A recipe for chocolate chip cookies calls for 2 1/3

Question

cups of flour. If you are making 1 1/3
recipes, how many cups of flour are​ needed?

The number of cups of flour needed to make 1 1/3
recipes of chocolate chip cookies is

Answer 1

3 1/2 cups of flour.

To find this answer, first calculate the amount of flour needed for one full recipe by multiplying 2 1/3 by 1 1/3:

2 1/3 x 1 1/3 = 7/3 x 4/3 = 28/9

Then, convert this fraction into a mixed number:

28 ÷ 9 = 3 with a remainder of 1

So, 1 1/3 recipes of chocolate chip cookies would require 3 cups of flour, and an additional 1/3 of a recipe would require 1/2 cup of flour. Therefore, the total amount of flour needed is:

3 cups + 1/2 cup = 3 1/2 cups of flour.
