Final answer:
To find out how many ounces are in 7 3/4 lbs, we convert 7 3/4 lbs to 31/4 lbs and then multiply it by 16 (since there are 16 ounces in a pound), resulting in 124 ounces. The correct option is D.
Step-by-step explanation:
The question asks us to convert 7 3/4 pounds (lbs) to ounces. We start with the unit equivalence that tells us 1 pound is equal to 16 ounces.
To find the number of ounces in 7 3/4 lbs, we convert the mixed number to an improper fraction which becomes 31/4 lbs. Then, we multiply this figure by the conversion factor of 16 ounces per pound.
To perform this calculation, we do the following:
- Convert 7 3/4 lbs to an improper fraction: (7 × 4) + 3 = 31/4 lbs.
- Multiply 31/4 by 16: (31/4) × (16/1) = 31 × 4 = 124 ounces.
So, 7 3/4 pounds is equal to 124 ounces, which corresponds to answer choice D.
