x = 3.1277777...
100x = 312.77777...
1000x = 3127.777777...
1000x - 100x = (3127.777..) - (312.777...)
900x = 3127 - 312 = 2815
x = 2815/900 = 563/180
Here is your answer,
==================================
Let
100x = 312.77777.............. (i)
1000x = 3127.77777.............. (ii)
(ii) - (i) = 3127.77777... - 312.77777...
1000x - 100x = 2815
900x = 2815
x = 2815/900 = 563/180
==================================
Hope it helps.
