✨Answer:✨

9 3/4 (simplest form)

✨Step-by-step explanation:✨

1. Convert decimal into fraction:

9.75 = 975/100

2. Simplify:

975/100 = 39/4 = 9 3/4

A. Reduce fraction to lowest terms (25 is the greatest common divisor of 975 and 100. Reduce by dividing both numerator and denominator by 25):

975/100 = 975 ÷ 25 = 39/4

100 ÷ 25

B. Convert improper fraction to mixed number:

39/4 = 9 3/4

(39 ÷ 4 = 9 remainder 3)

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.

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.

Malia : y = 8.1x.....this tells me she makes 8.10 per hr worked
