Вычислите:
а) $3\frac{1}{8} - 2\frac{2}{3} + \frac{1}{6}$;
б) $4\frac{3}{5} - 2 + \frac{1}{10}$;
в) $3\frac{7}{8} - 2\frac{3}{4} + \frac{1}{2}$;
г) $3\frac{5}{14} - 1 - \frac{6}{7}$.
$3\frac{1}{8} - 2\frac{2}{3} + \frac{1}{6} = 3\frac{3}{24} - 2\frac{16}{24} + \frac{4}{24} = 2\frac{27}{24} - 2\frac{16}{24} + \frac{4}{24} = \frac{27 - 16 + 4}{24} = \frac{15}{24} = \frac{5}{8}$
$4\frac{3}{5} - 2 + \frac{1}{10} = 2\frac{3}{5} + \frac{1}{10} = 2\frac{6}{10} + \frac{1}{10} = 2\frac{7}{10}$
$3\frac{7}{8} - 2\frac{3}{4} + \frac{1}{2} = 3\frac{7}{8} - 2\frac{6}{8} + \frac{4}{8} = 1\frac{7 - 6 + 4}{8} = 1\frac{5}{8}$
$3\frac{5}{14} - 1 - \frac{6}{7} = 2\frac{5}{14} - \frac{6}{7} = 2\frac{5}{14} - \frac{12}{14} = 1\frac{19}{14} - \frac{12}{14} = 1\frac{7}{14} = 1\frac{1}{2}$
