This question was posed by my math teacher to the class during a lean time in class for fun during my engineering days. This was my answer.
x = 0.999999....... (1)
10x = 9.999999....... (2)
Perform (2) minus (1)
9x = 9
x = 1
When I wrote it on the board, I still remember the awe in my friend's faces. And all I was doing was using the standard method to convert a recurring decimal into a fraction. :)
