Edit: the answer is correct only to 2 decimal digits (since equals sign has to be kept).

To be anal, I must point out that this only works to two digits of Pi. As soon as you hit 3 digits, the answer is wrong.
22 / 7 ~=
3.1428571428571428571428571428571
Pi ~=

22 / 7 ~=

Yes, I knew that it is not absolutely precise. Nevertheless, I like the way it's solved.

You could actually just remove one of the matchsticks from the divide sign and place it beside the other 2 on the right side of the equals sign. This allows for the most Correct answer possible.

You could also remove one of the matchsticks from the X in the top part of the equation, turning it into XIIII/VII=II (14/7=2).
the problem with your solution is that it is no longer a roman numeral. 4 in roman is IV, not IIII.

23/7 doesn't equal 3.

How about a non-equal sign?
I have to agree with this solution as being the best answer.
Never stoop to the level of idiots. They will drag you down and beat you with experience.
