All numbers greater than or equal to 0.5 and less than 1.5.
That would depend on what you are rounding to, if you have 369 you could round to the nearest 10s place and get 370 or you could round to the nearest 100s place and get 400. You round up when the number is greater than or equal to 5, and round down when it is less than 5.
399, 398, 397, 396, 395
When rounding to the nearest ten thousand half round up and half round down. Thus 10,000 ÷ 2 = 5,000 numbers either side of 520,000 round to it, ie 520,000 ± 5,000. However, as numbers exactly halfway round up: Thus any number greater than or equal to 515,000 and less than 525,000 round to 520,000 to the nearest ten thousand.
There are infinitely many numbers that are less than 30 and so it would be impossible to list them all.
950 to 999 would round to 1000 because 949 and less would round to 900.
1000.0
All numbers greater than or equal to 0.5 and less than 1.5.
Half of 10 is 5.So numbers in the range 800 ± 5 round to 800 to the nearest 10, except that numbers exactly half way round up. Thus all numbers greater than or equal to 800 - 5 round up to 800 and all numbers less than 800 + 5 round down to 800,That is all numbers greater than or equal to 795 and less than 805 will round to 800 to the nearest 10.
To round to the nearest hundred in 8143 you look to the last three digits 143 and if the number are less than 150 than you round down if the numbers are above 150 you round up so the answer to 8143 would be 8100.
That would depend on what you are rounding to, if you have 369 you could round to the nearest 10s place and get 370 or you could round to the nearest 100s place and get 400. You round up when the number is greater than or equal to 5, and round down when it is less than 5.
All numbers between 299.5 and 300.5, including 299.5 but excluding 300.5, round to 300 ( to the nearest integer; there are more numbers that fill the bill if you are rounding to the nearest multiple of 10 or 100).

Prime numbers
whole numbers would be 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.
No, 4 goes down. When rounding anything less than five you round down. When rounding anything five or more you round up. 4 is less than 5 so you round down. Rounding 4 down would be 0.
When rounding to the nearest ten thousand half round up and half round down. Thus 10,000 ÷ 2 = 5,000 numbers either side of 520,000 round to it, ie 520,000 ± 5,000. However, as numbers exactly halfway round up: Thus any number greater than or equal to 515,000 and less than 525,000 round to 520,000 to the nearest ten thousand.
