$1) \: \frac{6 - 5}{30} = \frac{1}{30}$

$2) \: \frac{3}{4} - \frac{1}{3} = \frac{9 - 4}{12} = \frac{5}{12}$

$3) \: \frac{7}{9} - \frac{2}{11} = \frac{77 - 18}{99} = \frac{69}{99} = \frac{23}{33}$

$4) \: \frac{3}{4} - \frac{4}{9} = \frac{27 - 16}{36} = \frac{11}{36}$

$5) \: \frac{7}{8} - \frac{5}{12} = \frac{21 - 10}{24} = \frac{11}{24}$

$6) \: \frac{11}{12} - \frac{11}{18} = \frac{33 - 22}{36} = \frac{11}{36}$
