Answer:
24lb 11oz , 4lb 4oz
Explanation:
The first question:
14lb + 9lb, or 14 + 9, = 23lb
15oz + 12oz, or 15 + 12, = 27oz
This means the answer is 23lb 27oz.
If it is asking for a simplified answer:
There are 16oz in 1lb.
27oz - 16oz = 11oz
So, the simplified answer would be 24lb 11oz.
The second question:
This is done the same way, just subtraction instead of addition.
14lb - 10lb = 4lb
10oz - 6oz = 4oz
This means the answer is 4lb 4oz.
This is the most simplified this answer can get.
