    i ) let x = 0.2323---( 1 )

    Multiply equation ( 1 ) with 100, we get

    100x = 23.2323-----( 2 )

    Subtract ( 1 ) from ( 2 ) , we get

    99x = 23

    x = 23/99 ----( 3 )

    ii ) Let y = 0.2222----( 4 )

    Multiply equation ( 4 ) with 100,

    100y = 22.2222-----( 5 )

    Subtract ( 4 ) from ( 5 ) , we get

    99y = 22

    y = 22/99 ----( 6 )

    Therefore ,

    0.23bar + 0.22bar

    = x + y

    = 23/99 + 22/99

    = ( 23 + 22 ) / 99

    = 45/99
    = 5/11
