Вычислите:
а) $1\frac{1}{2} - \frac{1}{6}$;
б) $1\frac{1}{4} - \frac{1}{2}$;
в) $1\frac{1}{5} - \frac{1}{4}$;
г) $1\frac{1}{6} - \frac{1}{5}$;
д) $1\frac{1}{9} - \frac{1}{6}$;
е) $1\frac{1}{8} - \frac{5}{6}$.
$1\frac{1}{2} - \frac{1}{6} = 1\frac{3}{6} - \frac{1}{6} = 1\frac{2}{6} = 1\frac{1}{3}$
$1\frac{1}{4} - \frac{1}{2} = 1\frac{1}{4} - \frac{2}{4} = \frac{5}{4} - \frac{2}{4} = \frac{3}{4}$
$1\frac{1}{5} - \frac{1}{4} = 1\frac{4}{20} - \frac{5}{20} = \frac{24}{20} - \frac{5}{20} = \frac{19}{20}$
$1\frac{1}{6} - \frac{1}{5} = 1\frac{5}{30} - \frac{6}{30} = \frac{35}{30} - \frac{6}{30} = \frac{29}{30}$
$1\frac{1}{9} - \frac{1}{6} = 1\frac{2}{18} - \frac{3}{18} = \frac{20}{18} - \frac{3}{18} = \frac{17}{18}$
$1\frac{1}{8} - \frac{5}{6} = 1\frac{3}{24} - \frac{20}{24} = \frac{27}{24} - \frac{20}{24} = \frac{7}{24}$
