Вычислите:
а) $|-\frac{2}{3}| + |\frac{4}{9}|$;
б) $|-\frac{2}{3}| - |-\frac{4}{9}|$;
в) $|-\frac{3}{5}| - |\frac{3}{25}|$;
г) $|-\frac{3}{5}| + |\frac{3}{25}|$;
д) $|\frac{13}{16}| + |-\frac{5}{8}|$;
е) $|\frac{13}{16}| - |-\frac{5}{8}|$.
$|-\frac{2}{3}| + |\frac{4}{9}| = \frac{2}{3} + \frac{4}{9} = \frac{6}{9} + \frac{4}{9} = \frac{10}{9} = 1\frac{1}{9}$
$|-\frac{2}{3}| - |-\frac{4}{9}| = \frac{2}{3} - \frac{4}{9} = \frac{6}{9} - \frac{4}{9} = \frac{2}{9}$
$|-\frac{3}{5}| - |\frac{3}{25}| = \frac{3}{5} - \frac{3}{25} = \frac{15}{25} - \frac{3}{25} = \frac{12}{25}$
$|-\frac{3}{5}| + |\frac{3}{25}| = \frac{3}{5} + \frac{3}{25} = \frac{15}{25} + \frac{3}{25} = \frac{18}{25}$
$|\frac{13}{16}| + |-\frac{5}{8}| = \frac{13}{16} + \frac{5}{8} = \frac{13}{16} + \frac{10}{16} = \frac{23}{16} = 1\frac{7}{16}$
$|\frac{13}{16}| - |-\frac{5}{8}| = \frac{13}{16} - \frac{5}{8} = \frac{13}{16} - \frac{10}{16} = \frac{3}{16}$
