A recipe for cookies calls for 7 and one half 7 1 2 cups of flour. If the recipe is for 22 dozen cookies, how much flour is needed for 1313 dozen cookies?
7.5/22 = x/1313
Solve for x.
To find out how much flour is needed for 13 dozen cookies, we can set up a proportion. Let's start by finding out how much flour is needed for 1 dozen cookies.
If the recipe calls for 7 1/2 cups of flour for 22 dozen cookies, we can divide the amount of flour by the number of dozens:
7 1/2 cups / 22 dozen = (15/2) cups / 22 = 15/2 * 1/22 = 15/44 cups
So, for 1 dozen cookies, we need 15/44 cups of flour.
Now, let's find out how much flour is needed for 13 dozen cookies. We can multiply the amount needed for 1 dozen by 13:
(15/44 cups/dozen) * 13 dozen = 15/44 * 13 = 195/44 cups
Therefore, for 13 dozen cookies, we'd need 195/44 cups of flour.
