The sum of 711 and 497 is calculated as follows:
**711 + 497 = 1,208**

To estimate, rounding 711 to 700 and 497 to 500 gives **700 + 500 = 1,200**. The exact sum (1,208) falls between **1,050 and 1,300**.

Explanation:
To estimate the sum of 711 and 497, we can round each number to the nearest hundred.
711 rounds up to 700, and 497 rounds up to 500.
The estimated sum is 700 + 500 = 1,200.
The only option that includes 1,200 is D: 1,050 and 1,300.

zhipu To estimate the sum of 711 + 497, let's round each number to the nearest hundred:

- 711 rounds to 700
- 497 rounds to 500

Now, adding these rounded numbers:

700 + 500 = 1200

So, the estimated sum is 1200, which falls between the numbers in option D.

deepseekv3 To estimate the sum of \(711 + 497\), we can round the numbers to the nearest hundred:

- \(711\) rounds to \(700\).
- \(497\) rounds to \(500\).

Adding these rounded numbers gives \(700 + 500 = 1,200\). Therefore, the sum is between \(1,050\) and \(1,300\).
