$\frac{1}{3} + \frac{5}{6} = \frac{2}{6} + \frac{5}{6} = \frac{7}{6} = 1\frac{1}{6}$
$\frac{3}{7} - \frac{2}{9} = \frac{27}{63} - \frac{14}{63} = \frac{13}{63}$
$\frac{7}{16} * \frac{8}{35} = \frac{1}{2} * \frac{1}{5} = \frac{1}{10} = 0,1$
$\frac{4}{9} * 18 = 4 * 2 = 8$
$\frac{46}{75} : \frac{23}{45} = \frac{46}{75} * \frac{45}{23} = \frac{2}{5} * \frac{3}{1} = \frac{6}{5} = 1\frac{1}{5}$
$\frac{2}{3} : 4 = \frac{2}{3} * \frac{1}{4} = \frac{1}{3} * \frac{1}{2} = \frac{1}{6}$
$10 : \frac{5}{11} = 10 * \frac{11}{5} = 2 * 11 = 22$
$2\frac{3}{8} + 4\frac{1}{6} = 2\frac{9}{24} + 4\frac{4}{24} = 6\frac{13}{24}$
$6 - 1\frac{3}{5} = 5\frac{5}{5} - 1\frac{3}{5} = 4\frac{2}{5}$
$4\frac{2}{7} - 1\frac{4}{9} = 4\frac{18}{63} - 1\frac{28}{63} = 3\frac{81}{63} - 1\frac{28}{63} = 2\frac{53}{63}$
$8\frac{3}{4} * 1\frac{3}{14} = \frac{35}{4} * \frac{17}{14} = \frac{5}{4} * \frac{17}{2} = \frac{85}{8} = 10\frac{5}{8}$
$1\frac{3}{5} : 5\frac{1}{3} = \frac{8}{5} : \frac{16}{3} = \frac{8}{5} * \frac{3}{16} = \frac{1}{5} * \frac{3}{2} = \frac{3}{10}$
