If you are rounding to hundreds, yes.
It is 450.
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.
350
It is closer to 400 because 5 and over are always going up to the next number in rounding. For example, if it was 453, it would round up to 500. But it is 432 so its 400.
449
If you are rounding to hundreds, yes.
It is 450.
There is no such number. Whatever number you choose, it is possible to find one that is even greater (closer to 400).
It is the target value less half the amount of rounding. If that sounds cryptic, try this example: Find the smallest number which, when rounded to the nearest 10 comes to 400. Target Value = 400 Amount of Rounding = 10 So the smallest value = 400 - 10/2 = 400 - 5 = 395. The smallest number rounded to the nearest 100, which comes to 400, is 400 - 100/2 = 400 - 50 = 350.
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.

9,999 is the greatest four digit number.
If you are rounding to hundreds, 418 is closer to 400 than 500.
395 is rounding to the nearest 10 is 400
