Well, isn't that a happy little question! When we round 500,000 to the nearest 100,000, we look at the digit in the ten-thousands place, which is 5. Since 5 is halfway between 0 and 10, we round up to the next hundred thousand, which gives us 600,000. Just like that, we've created a beautiful rounded number to work with!
