900 When rounding to the nearest hundred, like we did with 850 above, we use the following rules: A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above. B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below. C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
