To round to the nearest hundred and ten both being 200 it leaves 9 possibilities. 195,196,197,198,199,201,202,203, and 204. The only one with digits adding up to 19 is 199.
The number 47 does not have a digit in the hundreds place. It only has digits in the ones and tens places. The four is in the tens place and the seven is in the ones place. Therefore it cannot be rounded to the nearest hundreds place. The number 47 is between zero hundred and one hundred. It is nearer to zero hundred than it is to one hundred. When rounded to the nearest hundred, it becomes zero, since zero hundred is nearer to it than one hundred is.

The number would be 2666. 6 is repeated 3 times. Rounded to the nearest hundred is 2700 and rounded to the nearest thousand is 3000.
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.

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.
