To round off to the nearest hundred thousand, we look in the ten thousands column (the coluumn to the right of what we're trying to round to). Since there's a 4 in the ten thousands column, we will round down to get to the nearest hundred thousand. 798600000

To the nearest hundred thousand the number would be rounded down to zero. To the nearest hundred thousandth, which you may have meant, 3.00409 is the answer.
