$9 \frac{5}{51} - 3 \frac{2}{9} + 5\frac{7}{18} - 10 \frac{9}{34} = \frac{464}{51} - \frac{29}{9} + \frac{97}{18} - \frac{349}{34} = \frac{1392 - 493}{153} + \frac{97}{18} - \frac{349}{34} = \frac{899}{153} + \frac{97}{18} - \frac{349}{34} = \frac{1798 + 1649}{306} - \frac{349}{34} = \frac{3447}{306} - \frac{349}{34} = \frac{3447 - 3141}{306} = \frac{306}{306} = 1$
