  6. 0.123123123...

    123/10^3 + 123/10^6 + 123 /10^9 .....

    = (123/1000)(1 + 10^3 + 10^3*10^3 + 10*3*10*1*10^3 ......

    = (123/1000) (a + ar + 1 r^2 .....
    a = 1
    r = 1/1000

    is infinite geometric series
    sum = 1/(1-r)

    = 123/1000 (1/999/1000)
    123/999 on your calculator
