QUOTE(Magik6 @ Mar 13 2009, 01:14 PM)  I remember this, did it ages ago. If, 10X (= 9.999999) - X (= .999999) = 9X (= 9) Therefore X = 1 yay for me Apologies, I have a mild perpensity for OCD and therefore must make comment  Firstly only .99 RECURRING = 1 The notation should be a dot above the recurring number, but that can't be displayed in the forums, so I'll use the word 'recurring' instead  Easy Factorisation: x = .99 recurring 10x = 9.99 recurring 10x - x = 9.99 recurring - x 9x = 9.99 recurring - .99 recurring 9x = 9 x = 1 so .99 recurring = 1 I think the above is straight forward enough to not require an explanation (so shut it 5 )

a little easier to understand also. no need in a big long math prob.  .33recurring = 1/3 multiply both sides by 3.
