When you need to round a number. First you need to look at the placement number that the question is asking to round to the nearest. In this case it's the nearest hundred.
3,130,<u>6</u>49 the 6 is in the hundreds place. Now look to the number to the right of that number 3,130,6<u>4</u>9 that's the number that tells you if you will round up or down. If the number is 5 or more you round up, if it's less than 5 you round down.
In this case the 4 is less than 5 so you round down.
So your answer would be <u>3,130,600</u><u />
Hope this helps. :)

5: There is no number that would cause an imaginary number or make you divide by zero, meaning all real numbers are fine.
