12 lb 8 oz + 17 lb 8 oz

Question

A. 30 lb
B. 29one-half lb
C. 29 lb

Answer 1

To add the two weights, you can first add the pounds and then add the ounces separately.

Adding the pounds, we have:

12 lb + 17 lb = 29 lb

Then, adding the ounces, we have:

8 oz + 8 oz = 16 oz

However, 16 ounces is equivalent to 1 pound (since there are 16 ounces in a pound). So we can add this extra pound to the previous pounds sum of 29 lb, making a total of:

29 lb + 1 lb = 30 lb

Therefore, the answer is A. 30 lb.
