Answer 1

Округлять до тысяч 3,555

Answer 2

I can understand and communicate in Russian.

To round a number to the thousandths, you need to keep three digits after the decimal point and discard the rest. The fourth digit after the decimal point determines whether the previous digit stays the same or increases by one. If the fourth digit is 0, 1, 2, 3, or 4, the previous digit stays the same. If the fourth digit is 5, 6, 7, 8, or 9, the previous digit increases by one. For example:

- 3,5545 rounded to the thousandths is 3,555, because the fourth digit is 5, so the third digit increases by one. - 3,5544 rounded to the thousandths is 3,554, because the fourth digit is 4, so the third digit stays the same.
