Inspired by a video, Brooke decided to try a Filipino chicken recipe. The recipe requires 2 1/2 pounds of chicken. Brooke bought 5 3/4 pounds of chicken. How many pounds of chicken remain unused?

To find how many pounds of chicken are unused, we need to subtract the amount used from the total amount bought.

The amount used is 2 1/2 pounds of chicken, which is the same as 2.5 pounds.
The total amount bought is 5 3/4 pounds of chicken, which is the same as 5.75 pounds.

To find the amount unused, we subtract the amount used from the total amount bought: 5.75 pounds - 2.5 pounds = <<5.75-2.5=3.25>>3.25 pounds.

Therefore, there are 3.25 pounds of chicken remaining unused. Answer: \boxed{3.25}.

To find out how many pounds of chicken remain unused, we need to subtract the amount of chicken used in the recipe from the total amount of chicken Brooke bought.

The recipe requires 2 1/2 pounds of chicken, which is equivalent to 2.5 pounds. Brooke bought 5 3/4 pounds of chicken, which is equivalent to 5.75 pounds.

To find out how many pounds of chicken remain unused, we subtract 2.5 from 5.75:

5.75 - 2.5 = 3.25

Therefore, 3.25 pounds of chicken remain unused.

To find out how many pounds of chicken remain unused, we need to subtract the amount of chicken used from the total amount of chicken bought.

Step 1: Convert the mixed numbers to improper fractions.
- 2 1/2 pounds can be expressed as 5/2 pounds.
- 5 3/4 pounds can be expressed as 23/4 pounds.

Step 2: Subtract the amount of chicken used from the total amount of chicken bought.
- 23/4 - 5/2

Step 3: Find a common denominator.
- In this case, the common denominator is 4.

Step 4: Convert the fractions to have the same denominator.
- To convert 5/2 into a fraction with a denominator of 4, we multiply the numerator and denominator by 2: 5/2 = (5*2)/(2*2) = 10/4.
- So, the equation now becomes: 23/4 - 10/4.

Step 5: Subtract the numerators and keep the denominator.
- 23/4 - 10/4 = (23 - 10)/4 = 13/4 pounds.

Therefore, there are 13/4 pounds of chicken remaining unused. However, it might be more convenient to convert the improper fraction to a mixed number.

Step 6: Convert the improper fraction to a mixed number.
- The division of 13 by 4 is 3 with a remainder of 1. We can write this as 3 1/4.

Thus, Brooke has 3 1/4 pounds of chicken remaining unused.
