• let x=0.3434..... .....(1)
  
  then 100x=34.3434.... ....(2)
  
  (2)-(1)
  
  100x-x = 34.3434... - 0.3434...
  
  99x = 34
  
  x=34/99
  
  similarly 0.6969.... = 69/99
  
  0.8080... = 80/99
  
  0.4444... = 44/99
  
  0.3333... = 33/99
  
  0.07070... = 7/99
  
  (34+69+80-44-33-7)/99 =99/99 = 1
