      Even simpler

      0.99999999… = 1

      But you’re just restating the premise here. You haven’t proven the two are equal.

      1/3 =0.333333…

      This step

      1/3 + 1/3 + 1/3 = 0.99999999…

      And this step

      Aren’t well-defined. You’re relying on division short-hand rather than a real proof.
