**MathMate**, Friday, May 24, 2013 at 7:16pmIf you are working on the computer, you have to get the answer exactly right.

It asked for the answer to 2 decimal places. If you put three (3.625), it*could*mark you wrong.

On the other hand, there are two ways to round it to 2 decimal places.

Most people round it up when it is a 5 or more which is truncated, bringing it to 3.63.

The more meticulous way (such as accounting) would round it to an even number, which in this case would be 3.62. This is done to avoid indiscriminently rounding up which will cause a systematic error.
