To round to the nearest tenth of a number, you must determine if the current tenth or the next tenth is closest (less than 5 hundredths).

An example:

4.3946

Here, the three is the tenths place and the 9 is the hundredths place. The number is about nine hundredths away from being 4.3, but it is less than one hundredth away from being 4.4, so rounding to the nearest hundredth means rounding up to 4.4 in this case.

There is only one exception to that case, and that is if the hundredths place is a five. It is standard convention to round up in this case, always.
