А) $1 \frac{1}{2} - \frac{1}{6} = \frac{3}{2} - \frac{1}{6} = \frac{3*3}{2*3} - \frac{1}{6} = \frac{9}{2} - \frac{1}{6} = \frac{8}{6} = 1 \frac{2}{6} = 1 \frac{1}{3}$
б) $1 \frac{1}{4} - \frac{1}{2} = \frac{5}{4} - \frac{1*2}{2*2} = \frac{5}{4} - \frac{2}{4} = \frac{3}{4} = 0,75$
в) $1 \frac{1}{5} - \frac{1}{4} = \frac{6*4}{5*4} - \frac{1*5}{4*5} = \frac{24}{20} - \frac{5}{20} = \frac{19}{20} = 0,95$
г) $1 \frac{1}{6} - \frac{1}{5} = \frac{7*5}{6*5} - \frac{1*6}{5*6} = \frac{35}{30} - \frac{6}{30} = \frac{29}{30}$
д) $1 \frac{1}{9} - \frac{1}{6} = \frac{10*4}{9*4} - \frac{1*6}{6*6} = \frac{40}{36} - \frac{6}{36} = \frac{36}{36} = 1$
е) $1 \frac{1}{8} - \frac{5}{6} = \frac{9*3}{8*3} - \frac{5*4}{6*4} = \frac{27}{24} - \frac{20}{24} = \frac{7}{24}$
