To the nearest thousand: 1499 To the nearest hundred: 1049 To the nearest ten: 1005 With regards to rounding numbers ending in 5, I advocate rounding so that the previous digit becomes an even digit. If 5s are always rounded up [or down] you introduce an upward [downward] rounding bias. The suggested method avoids introducing a rounding bias and is reproducible by others.
To divide decimals the partial sums method requires that numbers are separated into individual portions. The separated numbers are then solved in long division until eliminated.
If you mean 8 1/2, you have to find the nearest integer. It is exactly between 8 and 9. Different rounding methods handle this different; a commonly used rounding method will always round up in this case.If you mean 8 1/2, you have to find the nearest integer.

To estimate 9.72, you can round the number to the nearest whole number, which would be 10. Another method is to round to the nearest tenth, which would be 9.7. You can also use compatible numbers, such as rounding 9.72 to 10 for easier mental calculations. These estimation techniques help simplify complex numbers for quick approximations.
Write both numbers as decimal numbers, then look for terminating decimals between the two.
