Вычислите:
а) $|\frac{1}{3} + \frac{1}{6}|$;
б) $|\frac{7}{12} - \frac{1}{4}|$;
в) $|\frac{4}{5}| + |-\frac{9}{10}|$;
г) $|-\frac{7}{8}| - |-\frac{1}{4}|$.
$|\frac{1}{3} + \frac{1}{6}| = |\frac{2}{6} + \frac{1}{6}| = |\frac{3}{6}| = |\frac{1}{2}| = \frac{1}{2}$
$|\frac{7}{12} - \frac{1}{4}| = |\frac{7}{12} - \frac{3}{12}| = |\frac{4}{12}| = |\frac{1}{3}| = \frac{1}{3}$
$|\frac{4}{5}| + |-\frac{9}{10}| = \frac{4}{5} + \frac{9}{10} = \frac{8}{10} + \frac{9}{10} = \frac{17}{10} = 1\frac{7}{10}$
$|-\frac{7}{8}| - |-\frac{1}{4}| = \frac{7}{8} - \frac{1}{4} = \frac{7}{8} - \frac{2}{8} = \frac{5}{8}$
