Answer:
9 lb + 9 oz
Step-by-step explanation:
4 lb 10 oz + 4 lb 15 oz
Add the two amounts of pounds together, then add the two amounts of ounces together.
4 lb 10 oz
+ 4 lb 15 oz
-------------------
8 lb 25 oz
The total weight is 8 lb and 25 oz. Since 25 oz is more than a pound, we convert 25 oz to pounds and ounces.
1 lb = 16 oz
25 oz - 16 oz = 9 oz
25 oz = 16 oz + 9 oz = 1 lb + 9 oz
Now we add 1 lb + 9 oz to 8 lb
8 lb + 0 oz + 1 lb + 9 oz = 9 lb + 9 oz
Answer: 9 lb + 9 oz
