\[\boxed{\mathbf{6.}}\]

\[\textbf{а)}\ |5| + | - 3| = 5 + 3 = 8\]

\[\textbf{б)}\ | - 3| + | - 5| = 3 + 5 = 8\]

\[\textbf{в)}\ | - 4| - | - 2| = 4 - 2 = 2\]

\[\textbf{г)}\ | - 1,6| + \left| - \frac{1}{4} \right| = 1,6 + 0,25 =\]

\[= 1,85\]

\[\textbf{д)}\ | - 34| \cdot \left| - \frac{2}{17} \right| = 34 \cdot \frac{2}{17} = 4\]

\[\textbf{е)}\ | - 27| \cdot \left| \frac{7}{9} \right| = 27 \cdot \frac{7}{9} = 21\]

\[\textbf{ж)}\ \left| - \frac{4}{5} \right| \cdot \left| - \frac{5}{8} \right| = \frac{4}{5} \cdot \frac{5}{8} = \frac{1}{2}\]

\[\textbf{з)}\ \left| \frac{7}{8} \right|\ :\left| - \frac{3}{4} \right| = \frac{7}{8} \cdot \frac{4}{3} = \frac{7}{6} = 1\frac{1}{6}\]

\[\textbf{и)}\ \left| - \frac{7}{12} \right|\ :\left| - \frac{5}{6} \right| = \frac{7}{12} \cdot \frac{6}{5} = \frac{7}{10} =\]

\[= 0,7\]

\[к)\ | - 5,75| + \left| - 2\frac{1}{4} \right| =\]

\[= 5,75 + 2,25 = 8\]
