  1. 0.725=725/1000=29/40
  2. 0.905=905/1000=181/200
  3. 0.004=4/1000=1/250
  4. 0.378...=378/999=27*14/(27*37)=14/37
  5. 0.51...=51/99=3*17/(3*33)=17/33
  6. 0.4884....=4884/9999=33*148/(33*303)=148/303
  7. 0.47666...=47.666.../100=47/100+(6/9)/100=47/100+2/300=(141+2)/300=143/300
  8. 0.27888...=27.888.../100=27/100+(8/9)/100=27/100+8/900=(243+8)/900=251/900
  9. 0.405444...=405.444.../100=405/1000+(4/9)/1000=405/1000+4/9000=(3645+4)/9000=3649/9000
  10. 0.378333...=378/1000+1/3000=(1134+1)/3000=1135/3000=227/600
