2 ¼ pounds of chicken
7 ¼ pounds of chicken
2 ½ pounds of chicken
2 2/4 pounds of chicken

Answer 1

To find the amount of chicken that remain unused, we need to subtract the amount used in the recipe from the total amount purchased.

Total amount of chicken purchased: 4 ¾ pounds
Amount used in the recipe: 2 ½ pounds

To subtract, we can convert both mixed fractions into improper fractions:
4 ¾ pounds = 4 + 3/4 = 16/4 + 3/4 = 19/4 pounds
2 ½ pounds = 2 + 1/2 = 10/2 + 1/2 = 11/2 pounds

Now, we subtract the amount used in the recipe from the total amount purchased:
19/4 pounds - 11/2 pounds

To subtract fractions, they must have the same denominator:
19/4 pounds = (19/4) * (2/2) = 38/8 pounds
11/2 pounds = (11/2) * (4/4) = 44/8 pounds

Now, we can subtract:
38/8 pounds - 44/8 pounds = -6/8 pounds

Since we have a negative answer, it means that the amount used in the recipe was more than the amount purchased. Therefore, there is no chicken remaining after making the tacos.

Answer: 0 pounds of chicken remain unused.
