Вычислите:
а) $1\frac{1}{2} - \frac{1}{2}$;
б) $1\frac{1}{5} - \frac{2}{5}$;
в) $1\frac{1}{4} - \frac{3}{4}$;
г) $1\frac{1}{6} - \frac{5}{6}$;
д) $1\frac{1}{9} - \frac{2}{9}$;
е) $1\frac{1}{8} - \frac{5}{8}$.
$1\frac{1}{2} - \frac{1}{2} = 1$
$1\frac{1}{5} - \frac{2}{5} = \frac{6}{5} - \frac{2}{5} = \frac{4}{5}$
$1\frac{1}{4} - \frac{3}{4} = \frac{5}{4} - \frac{3}{4} = \frac{2}{4} = \frac{1}{2}$
$1\frac{1}{6} - \frac{5}{6} = \frac{7}{6} - \frac{5}{6} = \frac{2}{6} = \frac{1}{3}$
$1\frac{1}{9} - \frac{2}{9} = \frac{10}{9} - \frac{2}{9} = \frac{8}{9}$
$1\frac{1}{8} - \frac{5}{8} = \frac{9}{8} - \frac{5}{8} = \frac{4}{8} = \frac{1}{2}$
