Best Answer

The '9' is in the "first decimal" place and the '3' is in the "second decimal" place.

Rules for rounding

- If the number in the second decimal place is 5 or greater then the number in the first decimal place is rounded upwards by 1.
- If the number in the second decimal place is 4 or less then the number in the first decimal place is left unchanged.

As the problem in this case is 3.93 and the number in the second decimal place is less than 5, we end up with

3.9 "correct to one decimal place" or "rounded to one decimal place".
