What is the rough estimate and closer estimate of 4125 + 139 + 62?
Let us find the estimate of the final answer of 4125 + 139 + 62.
Answer: The rough estimate is 4150 and the closest estimate is 4320.
Let us simplify the given problem by estimation.
Explanation:
The rough estimate is:
- 4125 is rounded off to 4000
- 139 is rounded off to 100
- 62 is rounded off to 50
The final rough estimate is 4160
The closer estimate is:
- 4125 is rounded off to 4120
- 139 is rounded off to 140
- 62 is rounded off to 60
The final rough estimate is 4320
Thus, the rough estimate is 4150 and the closest estimate is 4320.
