Oh, dude, 1200 rounded to the nearest hundred is like 1200. Because, you know, it's already a multiple of 100. So, like, no need to change anything. It's like saying, "Hey, that guy is already wearing pants."
Well, isn't that a happy little question! When we round 1200 to the nearest hundred, we look at the tens place. Since the digit in the tens place is 0, we keep the hundreds place the same and change the rest to zeros. So, 1200 rounded to the nearest hundred is 1200.
Oh honey, 1200 rounded to the nearest hundred is 1200. It's already sitting pretty at the nearest hundred, so no need to move it. Keep on shining, darling!
When rounding 1200 to the nearest hundred, we look at the digit in the tens place, which is 2. Since 2 is less than 5, we round down to 1200. So, 1200 rounded to the nearest hundred is still 1200.
