For this case we have the following number:
2,874,992
We want to round this number to the nearest ten thousand.
We then have the following rule:
1) If the number before the rounding place is less than 5, then the next number does not change.
2) If the number before the rounding place is greater than or equal to 5, then the next number increases by one.
Rounding the number we have:
2,874,992 = 2,870,000
Answer:
The rounded number for the nearest ten thousand is:
2,870,000
