Hundred (100) means the 3rd number from the right, which is: 249,982 . So use the number before that (further to the right) to determine whether you will round up or stay the same, which is 249,982
The number before the hundreds spot (8) is greater then 5, therefore we will round the number in the hundreds spot up 1
Since the number above 9 is 10 you will have to round the number in the thousands spot up as well
249,982
And it looks like the number in the thousands spot is 9 and the next number up is 10. This means you will have to round the number in the ten thousands place up 1
