Vamos lá:
a) 4,121212...
4+ 0,121212...
x=0,121212... *(100)
100x=12,121212...
100x=12+0,121212...
100x=12+x
99x=12
x= .
Assim, temos (4/33)+4=(136/33).
b) 2,818181...
2+0,818181...
x=0,818181... *(100)
100x=81.8181..
100x=81+x
99x=81
x=(9/11)--> Temos (9/11)+2=(31/11).
c) x=0,727272... *(100)
100x=72,727272..
100x=72+x
99x=72
x=(8/11)
d) 6,123123123...
6+0,123123123...
x=0,123123123... *(1000)
1000x=123,123123123...
1000x=123+x
999x=123
x=(41/333)--> Temos (41/333)+6=(2039/333).
Espero ter ajudado!
