What is the greatest whole number that rounds off to 82000?

Answer 1

Depends upon what you are rounding to.

To find the range of numbers when rounding to the nearest whatever (eg nearest 100) divide the whatever by 2 (eg in this case 100/2 = 50), then the smallest number which rounds to the given number (eg 1500) is the given number less the result of the division (eg in this case 1500 - 50 = 1450), and the largest is the given number plus the result of the division EXCEPT that numbers exactly half way round up, so the largest number is one less than the result of the addition (eg in this case 1500 + 50 - 1 = 1549).

To the nearest 82000, the largest whole number would be 82000 + 82000/2 - 1 = 122999

To the nearest 1000, the largest whole number would be 82000 + 1000/2 - 1 = 82,499

To the nearest 100, the largest whole number would be 82000 + 100/2 - 1 = 82049

To the nearest 10, the largest whole number would be 82000 + 10/2 - 1 = 82004
