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