Lots of calculations use 3 decimal places. A common example that you encounter often (but probably rarely think about it) is when you buy gasoline. The big sign may say 3.01 per gallon, but notice that little 9 after it. The actual price is $3.019
This doesn't exactly answer your question, since you want when the answer is 3 decimals, and the gas pumps always round to the nearest cent (2 decimals).
If you convert some fractions to a decimal, you can get 3 or more decimals as an answer: 3/8 = 0.375, for example.
Sales tax calculations can result in 3 or more decimal places (which are usually carried through to the final result, before rounding to 2 decimal places).
33.487 is already rounded to three decimal places. if it were 33.4829, which is four decimal places, you would round it to the nearest three DECIMAL places, which would be 33.487. So, the answer to your question is; 33.487 is already rounded to three decimal places.

Rounded to three decimal places, this is equal to 1.397.
Doesn't make sense because you only have 2 decimal places in the question. If you want the answer in three decimal places it would be 0.930 but that is not considered rounding.
.3328 rounded to four decimal places is .3328 .3328 rounded to three decimal places would be .333
Calculated and written to three decimal places: 0.024 Rounded to three decimal places: 0.025

0.080808 rounded to three decimal places is 0.081.
585.9607377 rounded to three decimal places is 585.961.
divide 52,562 by 59,874 and carry three decimal places
Just as it is. 0.581 is already rounded to three decimal places.
17.17642 rounded to three decimal places is 17.176.
0.017 is a number which is given to 3 decimal places. The equivalent number, at four decimal places, is 0.0170 but any number in the interval (0.0165, 0.0175), when rounded to four decimal places would give 0.017 to three.
As there is no decimal point in your set of numbers it is impossible to round it to three decimal places.
