Rounding up implies the number is smaller than 1000. However, a number smaller than 1000 cannot be a 4-digit number. So there cannot be such a number.
What was said is wrong. The greatest 4 digit number that rounds up is 999.9
1000
It depends on the degree of rounding. To the nearest integer, there is none. Otherwise 999.
1000
The greatest or largest 3 digit number is 999 because the next digit on the number line is 1000 a 4 digit number.
Any number 499 or less rounds to zero. Any number 500 or greater rounds to 1000.

949, which rounds down to 900.
1000
The digit in the hundreds position is 0, so the number rounds down to 22000.
The answer depends on the degree of rounding: to the nearest 10, 100, 1000, 5000?
999 is IM Roman numerals = 1000-1
The greatest product you can achieve by multiplying a 3-digit number by a 1-digit number is 9720, which comes from multiplying 972 (the largest 3-digit number less than 1000 when divided by 9) by 9 (the largest 1-digit number). Thus, the factors are 972 and 9.
