a recipe for 2 dozen cookies calls for 1 1/3 cups of flour.how much for would be needed to make five dozen cookies?
To determine how much flour would be needed to make five dozen cookies, we first need to find the ratio of flour to the number of cookies.
Given that the recipe for 2 dozen cookies requires 1 1/3 cups of flour, we can set up a proportion:
2 dozen cookies = 1 1/3 cups of flour
5 dozen cookies = ?
Let's solve for the unknown value.
2/1.33 = 5/x
Cross-multiplying:
2x = 1.33 * 5
2x = 6.65
Dividing both sides by 2:
x = 6.65 / 2
x ≈ 3.32
Therefore, approximately 3.32 cups of flour would be needed to make five dozen cookies.
To determine the amount of flour needed to make five dozen cookies, we can use the ratio method.
First, let's establish the ratio of flour to cookies. The original recipe calls for 2 dozen cookies and 1 1/3 cups of flour. This can be written as:
2 dozen cookies = 1 1/3 cups of flour
Since we want to know the amount of flour needed for 5 dozen cookies, we can set up a proportion using the ratio from the original recipe:
2 dozen cookies / 1 1/3 cups of flour = 5 dozen cookies / x
To solve for x (the unknown amount of flour), we can cross-multiply and then solve for x:
(2 dozen cookies) * x = (1 1/3 cups of flour) * (5 dozen cookies)
2x = (4/3) * 5
2x = 20/3
x = (20/3) / 2
x = 20/6
x = 10/3
Therefore, to make five dozen cookies, you would need 10/3 cups of flour. This simplifies to approximately 3 1/3 cups of flour.
2/(1 1/3) = 5/x
Cross multiply and solve for x.
