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