А) $2 \frac{5}{18} - \frac{5}{6} = \frac{41}{18} - \frac{5}{6} = \frac{41}{18} - \frac{15}{18} = \frac{26}{18} = \frac{13}{9} = 1 \frac{4}{9}$
б) $3 \frac{2}{5} - \frac{11}{15} = \frac{17}{5} - \frac{11}{15} = \frac{51}{15} - \frac{11}{15} = \frac{40}{15} = \frac{8}{3} = 2 \frac{2}{3}$
в) $1 \frac{4}{5} - \frac{9}{10} = \frac{9}{5} - \frac{9}{10} = \frac{18}{10} - \frac{9}{10} = \frac{9}{10} = 0,9$
г) $\frac{7}{24} + \frac{5}{24} = \frac{12}{24} = \frac{1}{2} = 0,5$
д) $\frac{17}{18} - \frac{5}{18} = \frac{12}{18} = \frac{6}{9} = \frac{2}{3}$
