When rounding 583 to the nearest hundreds, we look at the digit in the hundreds place, which is 5. Since the digit to the right of the hundreds place is 8 (greater than or equal to 5), we round up. Therefore, 583 rounded to the nearest hundreds is 600.
Well, darling, 583 rounded to the nearest hundreds is 600. It's not rocket science, honey. Just bump that number up if it's 5 or more, and keep it the same if it's less. Easy peasy lemon squeezy!
