  1. $\frac{8 . 17 + 17 + 2 . 17}{15 . 33 + 2 . 33}$
    = $\frac{17 . (8 + 1 + 2)}{33 . (15 + 2)}$
    = $\frac{17 . 11}{33 . 17}$
    = $\frac{11}{33}$
    = $\frac{1}{3}$
     

  2. \frac{8.17+17+2.17}{15.33+2.33}
    =\frac{17 . (8 + 2 + 1)}{33.(15+2)}
    =\frac{17.11}{33.17}
    = 11/33
    = 1/3
