Final answer:
The total weight of the books is 6 pounds. This was calculated by converting all weights to ounces, summing them, and then converting the total back to pounds and ounces.
Explanation:
The weight of the books you've mentioned is given in pounds (lb) and ounces (oz). To find the total weight, it's easiest to convert everything to the same unit. First, convert the weights given in pounds and ounces to ounces alone. Since 1 pound is equivalent to 16 ounces, we can rewrite 1 lb 7 oz as 23 oz (16+7), 1 lb 2 oz as 18 oz (16+2) and 1 lb 3 oz as 19 oz (16+3). Then, add these values to the weights provided solely in ounces.
- Book 1: 12 oz
- Book 2: 23 oz
- Book 3: 18 oz
- Book 4: 15 oz
- Book 5: 9 oz
- Book 6: 19 oz
When you add all these weights together, you get a total of 96 oz. We can convert this back to pounds and ounces by realizing there are 16 oz in 1 lb. 96 oz becomes 6 pounds with no remainder, so the total weight of these books is 6 lb.
