Answer:
5462.955
Explanation:
The first number after the decimal is the tenth place, next is hundredth place and right after that is the thousandth place.
To round to the thousandth place, we consider the tenth thousand placed figure.
If this is not up to 5, we cut off otherwise, we add 1 to the number in the thousandth place.
As such, when 5462.9554 rounded to the thousandth place, the result is 5462.955.
