Thread: Tersonian decimal expansion? View Single Post
 P: 8 1. The problem statement, all variables and given/known data 1/7=? 2. Relevant equations 3. The attempt at a solution Consider $$y=\overline{145827}.0=\dots145827145827145827.0$$, then $$1000000y=\dots 145827145827000000.0$$ and $$-999999y=145827$$ . Therefore, $$y=-\dfrac{145827}{999999}$$ . Son in fact $$\overline{145827}.0$$ is a "negative" number. $$\dfrac{1}{7}=-\overline{145827}.0$$ However, There is no minus in Tersonian decimal expansions?? How can I show 1/7 in Tersonian decimal expansion??
