    (-2/3)^2 – 7/4 + (9/4 + 11/18 : 23/12)
    = 4/9 – 7/4 + 9/4 + 22/69
    = 4/9 – (7/4 – 9/4) + 22/69
    = 4/9 + 1/2 + 22/69
    = 17/18 + 22/69
    = 391/414 + 132/414
    = 523/414

    ( -2/3)^2 – 7/4 + ( 9/4 + 11/18: 23/12)
    =4/9−7/4+9/4+22/69
    =4/9+(7/4−9/4)+22/69
    =4/9+1/2+22/69
    =17/18+22/69
    =523/414
