Question

Obtenha a fração irredutível equivalente a:
0,262626...
2,176176176...
0,12666....

Answer 1

x = 0,262626      100x = 26,2626
100x -  x = 26,2626 - 0,2626
99x =26
x = 26 / 99

x = 2,176176176       1000x = 2176,176176
1000x - x = 2176,176176 - 2,176176
999x = 2174
x = 2174 / 999

x = 0,12666     100x = 12,666       1000x = 126,666
1000x - 100x = 126,666 - 12,666
900x = 114
x = 114 / 900 >>> 19 /150
