Assuming you are dealing with whole numbers only: Half of the numbers round up and half round down. Half of ten thousand is five thousand. Therefore 400000 ± 5000 round to 400000 to the nearest 10000; except that numbers exactly half way round up, so the maximum is one less than this. → smallest to round [up] to 400000 is 400000 - 5000 = 395000 → largest to round [down] to 400000 is 400000 + 5000 - 1 = 404999
8,500 and 9,499
5500 to 6499
To solve this, you have to consider what the largest and smallest numbers could be to cause the ten thousand's place to round to a 0.404,444 is the largest, because if you round to the ten thousand's place, it will still be 400,000. If any of the 4s becomes a 5, it will round up to 410,000.394,445 is the smallest, because if you round to the ten thousand's place, it will round up to 400,000

45 and 54
When rounding to the nearest 10,000 , all whole numbersfrom 5,000 to 10,499 round to 10,000 .
The largest whole number is 3499
The smallest number to round to 10000 is 5000. The largest number is 14999.
45 to 54
They are 14 and 5
smallest possible whole number is 6500
350 to 449
When rounding to the nearest whatever, half the number round up and half round down. → the numbers that round to 170000 to the nearest 10000 are 170000 ± (10000 ÷ 2) = 170000 ± 5000 However, if a number is exactly half way, the convention is to round them up, so the numbers in the range: 170000 - 5000 ≤ number < 170000 + 5000 → 165000 ≤ number < 175000 will round to 170000 to the nearest 10000 → smallest number is 165000 → biggest [whole] number is 175000 - 1 = 174999
