Abaker is using a cookie that calls for 2 1/4 cups of flour to yield 36 cookies, how much flour will the baker neeto to make 90 cookies using the same recddipe?

cups

Step-by-step explanation:

Given: A baker is using a cookie that calls for 2 cups of flour to yield 36 cookies.

To find the number of flour will the baker need to make 90 cookies, we form a proportion.

Let's convert 2 to improper fraction.

Let "x" be the amount flour to make 90 cookies

Amount of Flour                 Number of cookies

                                36

       x                                            90

Now form a proportion.

Now let's cross multiply, we get

Now let's simplify the fraction part, Here the GCF of 90 and 144 is 18, so dividing the fraction's numerator and the denominator by 18, we get

x = cups

So the baker needs cups to make 90 cookies.
