When rounding 9.999 to the nearest thousandth, it remains 9.999. When rounding to the nearest hundredth, it becomes 10.00. Rounding to the nearest tenth gives us 10.0, and rounding to the nearest one results in 10.

Since 115.9 percent is rounded to a tenth of a percent, it is already rounded to the nearest thousandth.115.9 is rounded to the nearest tenth. Rounded to the nearest thousandth it becomes 115.900
When rounding 9.999 to the nearest thousandth, it remains 9.999. When rounding to the nearest hundredth, it becomes 10.00. Rounding to the nearest tenth gives us 10.0, and rounding to the nearest one results in 10.

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
