If you're talking about whole numbers, then it's 6,049 .If you're talking about any number, including decimals and fractions, then there's no "greatest possible" one.
3400 We round the number up to the nearest hundred if the last two digits in the number are 50 or above. We round the number down to the nearest hundred if the last two digits in the number are 49 or below. If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
Assuming the answer is a positive integer then the range of integers that round to 5600 to the nearest hundred is 5550 to 5649. As the first two digits sum to 10 or 11, then the questioner may be able to find the answer by elimination.
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.
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above. 8400 is the answer

Remember, we don't necessarily round up or down, but to the hundred that is closest to 2153. When rounding a number like 2153 to the nearest hundred, we use the following rules: a) We round the number to the nearest hundred if the last two digits of the number are 50 or more.
555
Remember, we did not necessarily round up or down, but to the hundred that is nearest to 321. First, 321 rounded to the nearest hundred is: 300 When rounding to the nearest hundred, like we did with 321 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.

The mystery number is 155. When rounded to the nearest hundred, it rounds to 200. The sum of its digits is 1+5+5=11 which is greater than 10, so we must adjust the digit in the hundreds place. When rounded to the nearest ten, 155 rounds to 160, which has digits summing up to 1+6+0=7.
