What would 897,100 be if rounded to the nearest ten thousand?

Answer is 900,000.

Explanation;

To round off the numbers we should know the place values of the digis. The place values of the digits in 897,100 are as follows

8                                           9                        7                   1                0        0

↑                                           ↑                        ↑                    ↑                ↑        ↑

Hundred thousands   Ten thousands   Thousands   Hundreds   Tens   ones

To round off nearest ten thousand we should look at the digit after the ten thousands place means thousands place.

If the digit is thousands place is smaller than 5, the ten thousands place will not be changed. But that digit is equal or larger than 5, 1 should be added to the ten thousands place.

The digit in thousands place is 7. It is greater than 5. Hence, 1 should be added to the digit in ten thousands place. Then 1 + 9 = 10. Hence, answer is 100,000.
