Standard rounding of 468 to the nearest thousandth: 0
(because 468 is smaller than 500. If it were bigger or equal to 500, then you'd need to round up).
There are several other rounding techniques, for example in physics, it is often usual to round in a way that the relative error would be minimized (in that case, the answer would be 1000). Or stochastical rounding would non-deterministically either give 0 or 1000 (where 0 would have a chance of 46.8%, i.e. slightly smaller than the chance for 1000). But most probably the answer you're looking for is 0.
All of that may be true to the nearest thousand. 468 is already rounded to the nearest thousandth, but may be written as 468.000
.333
90% = 0.900 to the nearest thousandth.
The first numeral after the decimal place is tenths. The second is hundredths, and the third is thousandths. 0.18 is already rounded up to the nearest thousandth; you can't round it up because there is no ten thousandths to round it up from. Sorry; this is a little confusing.
To the nearest thousand: 2000 To the nearest thousandth: 2032.000
It depends: If you round to the nearest unit: 1500.4 If you round to the nearest 10: 1504 If you round to the nearest 100: 1549
