Explicação passo-a-passo:
Aplique a geratriz:
a)1,23333...
x=1,23333..
10x=12,33333....
100x=123,33333...
100x=123,3333...
- 10x= 12,3333...
---------------------------
90x= 111
x= 111/90
b)0,12626...
x=0,12626...
10x=1,2626...
100x= 12,6262...
1000x=126,26262
1000x= 126,26262...
- 10x= 1,26262....
-------------------------------------
990x= 125
x=125/990
x=25/198
c-)x=0,5555....
10x=5,555...
10x= 5,555...
- x= 0,5555
---------------------
9x= 5
x=5/9
Resposta:
a) 1,2333....
x=1,2333.....
10x=12,333...
100x=123,333...
100x-10x=123-12
90x=111
x=111/90
b)0,1262626...
x=0,1262626...
10x=1,262626....
1000x=126,2626...
990x=126-1
990x=125
x=125/990
c)0,5555....
x=0,555...
10x=5,555..
10x-x=5-0
9x=5
x=5/9
d)1,25
125/100
5/20
1/4
e)52,3= 523/10
f) 0,00002
2/100000
1/50000
