If Trish needs 1/4 cup of butter for a dozen cookies, how much does she need for 9 dozen?

To determine how much butter Trish needs for 9 dozen cookies, we start with the amount she needs for 1 dozen cookies, which is 1/4 cup. Since she wants to make 9 dozen, we need to multiply the amount of butter required for one dozen by the number of dozens she plans to make.

We can calculate it as follows:

1. Start with the amount of butter per dozen: 1/4 cup.

2. Multiply by the total number of dozens she wants: 9 dozen.

So the calculation is:

(1/4 cup) * 9 = 9/4 cups.

Next, we convert 9/4 to a mixed number:

9 divided by 4 equals 2 with a remainder of 1, which can be expressed as 2 1/4.

Thus, Trish needs 2 1/4 cups of butter to make 9 dozen cookies. This makes the answer accurate and ensures she's using the correct proportional measurement based on how many cookies she intends to bake.
