Question

Fiona is making alfredo sauce. She typically makes it by using 4 cups of heavy cream combined with 36 ounces of parmesan cheese.

How many cups of heavy cream does she need for every ounce of parmesan cheese?

Answer 1

0.111... cups

Step-by-step explanation:

Set the two quantities equal to each other

4 cups = 36 ounces

Notice it says "every ounce",

so we're looking for how many cups are needed for "1 ounce of parm"

(?) cups = 1 ounce

we know the ratio is 4 to 36

4 = 36

(?) = 1

36/(?) = 1, ? 3 = 36

find 4/36

0.111... cups

Answer 2

Fiona uses about 7.11111 ounces of heavy cream for every ounce of parmesan cheese in her alfredo sauce recipe. To calculate this, the ratio of cups of heavy cream to cups of parmesan cheese (4 cups to 4.5 cups) was determined and then converted to ounces.

Step-by-step explanation:

The student's question is about determining the ratio of heavy cream to parmesan cheese that Fiona uses in her alfredo sauce recipe. Fiona uses 4 cups of heavy cream with 36 ounces of parmesan cheese. To find out how many cups of heavy cream she needs for every ounce of parmesan cheese, we need to establish a ratio between the two ingredients.

First, we will express the amount of cheese in cups, knowing that 1 cup equals 8 ounces. Since Fiona uses 36 ounces of parmesan cheese, we can calculate the number of cups as follows:

36 ounces ÷ 8 ounces per cup = 4.5 cups of parmesan cheese.

With this information, we can set up the ratio of heavy cream to parmesan cheese:

4 cups heavy cream / 4.5 cups parmesan cheese = 0.888889 cups of heavy cream per cup of parmesan cheese.

To convert this to a per ounce ratio, since each cup of parmesan cheese is equivalent to 8 ounces, we multiply the ratio by 8:

0.888889 cups of heavy cream × 8 ounces per cup = 7.11111 ounces of heavy cream per ounce of parmesan cheese.

Therefore, Fiona needs approximately 7.11111 ounces of heavy cream for every ounce of parmesan cheese.
