A recipe for oatmeal cookies makes 24 cookies. The recipe calls for 2 1/2 cups of flour. Penny wants to make 3/4 of the recipe.
barxatty [35]

Answer:

Penny needs 1\frac{7}{8} cups of flour to make 3/4 of the recipe.

The recipe will make 18 cookies.

Step-by-step explanation:

We have been given that a recipe for oatmeal cookies makes 24 cookies. Penny wants to make 3/4 of the recipe.

To find the number of cookies that will 3/4 of the recipe will make, we need to find 3/4 of 24 as shown below:

\frac{3}{4}\text{ of recipe}=24\times \frac{3}{4}

\frac{3}{4}\text{ of recipe}=6\times \frac{3}{1}

\frac{3}{4}\text{ of recipe}=18

Therefore, the recipe will make 18 cookies.

We are also told that recipe calls for 2 1/2 cups of flour. To find amount of flour needed for 3/4 of the recipe, we will multiply 2 1/2 cups by 3/4 as:

\text{Cups of flour needed to make 3/4 of recipe}=2\frac{1}{2}\times \frac{3}{4}

\text{Cups of flour needed to make 3/4 of recipe}=\frac{5}{2}\times \frac{3}{4}

\text{Cups of flour needed to make 3/4 of recipe}=\frac{5\times 3}{2\times 4}

\text{Cups of flour needed to make 3/4 of recipe}=\frac{15}{8}

\text{Cups of flour needed to make 3/4 of recipe}=1\frac{7}{8}

Therefore, Penny needs 1\frac{7}{8} cups of flour to make 3/4 of the recipe.
