Answer:

Suppose that the value of x=6.12ˉ

now, x=6.12121212−−−−

multiplay 100 on both side

then,

100x=6.121212−−−−−

100x=606+6.121212−−−−−

100x=606+x

100x−x=606

99x=606

x=99606

x=33203

then, the deniminoter is 33

Hence, this is the answer

Verified answer

Answer:

Let the value of x = 6.12 bar

x = 6.121212121 ...

Multiply 100 on both side

100 x=612.12121212121..

100x = 606 + 6.12121212 ...

100x = 606 + x

100x - x = 606

99x = 606

X = 606/99 = 203/33

X = 606/99 = 203/33

The rational nber=101^ * 2/3^ * 11
