Final answer:
The comparison between 819 and 85 alone is insufficient to determine which measurement is larger.
Step-by-step explanation:
The comparison between 819 and 85 is incorrect. Although 819 is a larger number than 85, it does not necessarily mean that Jason's measurement is larger than Marco's. The context of the measurement needs to be considered.
For example, if Jason's measurement is in meters and Marco's measurement is in kilometers, then Marco's measurement is larger because 1 kilometer is equal to 1000 meters.
Therefore, the comparison between 819 and 85 alone is insufficient to determine which measurement is larger. The units of measurement also need to be taken into account.
