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
8,500 and 9,499

The answer depends on the degree of rounding. To the nearest fifty, the range is 325 < X < 375.
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
29500 to 30499
The smallest number would be 29500. The largest number would be 31499.
85000 and 94999
8000
The wording of this question seems confusing. 5700 rounded to the nearest thousand would be 6000. So you appear to be looking for the largest and smallest whole numbers that would round to 6000.The smallest whole number that would round to 6000 would be 5500. 5499 if rounded to the nearest thousand would be 5000.The largest whole number that would round to 6000 would be 6499. 6500 if rounded to the nearest thousand would be 7000.
I believe the answers are 165,000 and 174,999
