41111333000
Let x=0.123¯¯¯¯¯¯¯¯456
Multiply the above equation with 1000 and 1000000, we get two equations;
1000x=123.¯¯¯¯¯¯¯¯456 ........................(1)
1000000x=123456.¯¯¯¯¯¯¯¯456 .....................(2)
Subtracting (1) from (2),
1000000x−1000x=123456.¯¯¯¯¯¯¯¯456−123.¯¯¯¯¯¯¯¯456
we get, 999000x=123333
x=123333999000=41111333000
