To find a rough estimate and a closer estimate of the numbers 4125, 139, and 62, we can round each number to make calculations simpler.
Rough Estimate: For a rough estimate, we can round each number to the nearest hundred or thousand, depending on their size.
- 4125 rounds to 4100
- 139 rounds to 100
- 62 rounds to 100
Now, we can add these rounded numbers:
4100 + 100 + 100 = 4300
Closer Estimate: For a closer estimate, we can round to the nearest ten or hundred where appropriate:
- 4125 rounds to 4120
- 139 rounds to 140
- 62 rounds to 60
Now, we add these numbers:
4120 + 140 + 60 = 4320
In summary, the rough estimate is 4300 and the closer estimate is 4320.
