This is a really tricky one to get your head around. Professional mathematicians have accepted that 0.(9) does equal 1 because each real number does not have to have a unique decimal expansion, nonzero infinitesimal real numbers son't always have to exist, and the expansion of 0.(9) never terminates. The mathematical proof is as follows: 1 = 9/9 = 9x(1/9) = 9x0.(1) = 0.(9) Since the equation is valid, 0.(9) must equal 1. Side: .999999 =1
