The answer is:
% i \/ H+ h {6 q$ n* W# s: w4 otvb now,tvbnow,bttvb$ x: B2 b1 |# K4 r% R
If 1/9=0.1...(循環)
6 v5 F# |% g3 g1 c* utvb now,tvbnow,bttvband then 2/9=0.2....(循環)
% ]5 T' F) l( Y& n1 B8 \and then 3/9=0.3....(循環)- `7 U, J; T4 j: ~/ H3 ^
and then 4/9=0.4....(循環)5.39.217.77: h' F8 s# `/ ` s/ w4 T; I" Q/ [
.......6 G- B! \# w, J# \$ g5 D
and then 8/9=0.8....(循環)
$ q, o! T3 c( y7 [6 z5.39.217.775.39.217.77% D+ W9 Y0 k m
So, 9/9=0.9....(循環) =1 |
