Around off 124,607 to the nearest hundred thousand

The answer will be 125,000

The digit in the hundred thousandth's place is a one, so you look to the right. The next digit is a two, so you'd round down because if the next digit to the right is or is higher than five, you round up. If it is, or is lower than four, you'd round down. So ultimately, you'd round down and the answer would be 100,000.
