What are the largest and the smallest round to 400000 by ten thousand?

Answer 1

395000

Answer 2

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
