Final answer:
After converting 9 pounds to ounces, which equals 144 ounces, we can conclude that 9 pounds is heavier than 128 ounces.
Explanation:
The question posed is a comparison between two different measurements of weight: 128 ounces and 9 pounds. To determine which is heavier, we should convert the measurements to the same unit. Knowing that there are 16 ounces in a pound, we can convert 9 pounds to ounces.
By multiplying 9 (the number of pounds) by 16 (the number of ounces in a pound), we get:
- 9 × 16 = 144 ounces
Having converted 9 pounds to ounces, it is clear that 144 ounces is heavier than 128 ounces. Therefore, 9 pounds is heavier than 128 ounces.
