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.
