Question: solve returns a strange answer

Hi all, I am a teacher of middle/high school math. I have found that when I use the solve function on:


I get 5.674999999

In fact, as I was typing the above equation just now using Maple Math, I noticed it returns:


even though I typed 1.5 at the end.

Any idea what I can do to make it return 5.675 or even 227/40?

Please do not suggest that I change the equation to fractions purely. Thanks.
