It is 999, exactly as in the question.
1,000
It is: 1,000
100
To the nearest thousand, 57000
30,000,000
30,000,000
You can round up 999 to the nearest tens (that is 1000). This is only applicable when you are doing a calculation involving very huge value, where using 1000 or 999 will have negligible effect on the final answer.
Well, isn't that just a happy little question! When we round 999 to the nearest thousand, we see that it's closer to 1000 than it is to 0. So, we round it up to 1000. Just like adding a little touch of paint to finish a beautiful landscape, rounding 999 to 1000 helps us see the big picture in a simple and clear way.
The 5 will round the 2 up to 3, giving 0.123 as the result.
You would round it UP - to read 10.00
It depends on the magnitude to which it is rounded. To the nearest integer (or smaller) it is 9 999 999 To the nearest 10, 100, etc to 10 million, it is 10 000 000 000 To the nearest 100 million or larger, it is 0
