C. 16 lbs 19 oz
D. 16 lbs 9 oz

Answer :

Final answer:

To solve 9 lbs 5 oz + 7 lbs 14 oz, we first combine ounces and convert excess to pounds resulting in 17 lbs and 3 oz, hence the correct answer is not in the options provided.

Explanation:

To solve the addition of 9 lbs 5 oz + 7 lbs 14 oz, we work with both pounds and ounces separately. Since there are 16 ounces in one pound, we start by combining the ounces. 5 oz + 14 oz equals 19 oz, which is more than 16, so we can convert some ounces into pounds.

19 oz is equivalent to 1 lb 3 oz because we take 16 oz out of 19 oz to make an extra pound. This means the sum in ounces is 1 lb 3 oz.

Next, we add the sum of the pounds: 9 lbs + 7 lbs + the extra 1 lb from the ounces, which gives us, 17 lbs. Therefore, including the remaining 3 ounces, the final answer is 17 lbs 3 oz.
