Answer :

992,449 rounded to the nearest hundred thousands is 1,000,000. The reason why is because the 9 in the ten thousands place is pushing up the 9 in the hundred thousands place. 



For this case we have the following definition:

hundred thousands place: number of 6 digits greater than zero.

 Then, we have two rules:

1) If the previous number is greater than or equal to five, then the next number increases one unit.

2) If the previous number is less than five, then the next number stays the same

We have the following number:

992,449  

Rounding to the nearest hundred thousands we have:

1,000,000

Answer:

992,449  to the nearest hundred thousands is:

1,000,000
