To round 880,005 to the nearest hundred thousand, we need to consider the digit in the hundred thousand place, which is 8 in this case.
Since the digit 8 is greater than or equal to 5, we round up the digit in the hundred thousand place, which becomes 9. The digits in the places to the right of the hundred thousand place are dropped or become zeros.
Therefore, rounding 880,005 to the nearest hundred thousand gives us 900,000.
