$\frac{5}{6} - \frac{3}{22} = \frac{55}{66} - \frac{9}{66} = \frac{55 - 9}{66} = \frac{46}{66} = \frac{23}{33}$$0,75 - (\frac{3}{16} + \frac{1}{24}) = \frac{3}{4} - (\frac{9}{48} + \frac{2}{48}) = \frac{3}{4} - \frac{11}{48} = \frac{36}{48} - \frac{11}{48} = \frac{25}{48}$

$\frac{9}{16} + (0,25 - \frac{5}{24}) = \frac{9}{16} + \frac{1}{4} - \frac{5}{24} = \frac{27}{48} + \frac{12}{48} - \frac{10}{48} = \frac{29}{48}\\\\ 0,88 - \frac{2}{15} = \frac{22}{25} - \frac{2}{15} = \frac{66}{75} - \frac{10}{75} = \frac{56}{75} \\\\(\frac{1}{6} + \frac{5}{18}) - (\frac{1}{18} + \frac{1}{24}) = (\frac{3}{18} + \frac{5}{18}) - ( \frac{1}{18} + \frac{1}{24}) = \frac{8}{18} - (\frac{4}{72} + \frac{3}{72}) = \frac{8}{18} - \frac{7}{72} = \frac{32}{72} - \frac{7}{72} =$

$\frac{25}{72} \\4 - 2\frac{4}{7} = 3\frac{7}{7} - 2\frac{4}{7} = 1\frac{3}{7} \\\\2,5 + 1\frac{2}{3} - 3\frac{1}{6} = 2\frac{1}{2} + 1\frac{2}{3} - 3\frac{1}{6} = 2\frac{3}{6} + 1\frac{4}{6} - 3\frac{1}{6} = 1\\\\0,36 - \frac{9}{75} + \frac{2}{15} = \frac{9}{25} - \frac{9}{75} + \frac{2}{15} = \frac{27}{75} - \frac{9}{75} + \frac{10}{75} = \frac{28}{75} \\\\( \frac{1}{2} - \frac{1}{3}) - (\frac{1}{4} - \frac{1}{5}) = (\frac{3}{6} - \frac{2}{6}) - (\frac{5}{20} - \frac{4}{20})=\frac{1}{6} -\frac{1}{20}$$= \frac{10}{60} - \frac{3}{60} = \frac{7}{60} \\\\3\frac{2}{9} + 4\frac{1}{6} - 1\frac{8}{27} = 3\frac{12}{54} + 4\frac{9}{54} - 1\frac{16}{54} = 6\frac{5}{54} \\\\11 - 6\frac{2}{3} -3 \frac{5}{7} = 10\frac{21}{21} - 6\frac{14}{21} - 3 \frac{15}{21} = 9\frac{42}{21} - 6\frac{14}{21} - 3 \frac{15}{21} = \frac{13}{21} \\\\5\frac{7}{12} - 2\frac{4}{9} + 1\frac{5}{18} = 5\frac{21}{36} - 2\frac{16}{36} + 1\frac{10}{36} = 4\frac{15}{36} = 4\frac{5}{12}$

$\frac{27}{75} + 0,32 - \frac{7}{15} = \frac{27}{75} + \frac{8}{25} - \frac{35}{75} = \frac{27}{75} + \frac{24}{75} - \frac{35}{75} = \frac{16}{75}\\ \\(\frac{1}{3} - \frac{1}{4}) - (\frac{1}{5} - \frac{1}{6}) = (\frac{4}{12} - \frac{3}{12}) - (\frac{6}{30} -\frac{5}{30}) = \frac{1}{12} - \frac{1}{30} = \frac{5}{60} - \frac{2}{60} = \frac{3}{60} = \frac{1}{2}$
