\[\boxed{\mathbf{10.}}\]

\[\textbf{а)}\ \left| - \frac{1}{2} \right| + \left| \frac{3}{4} \right| = \frac{1}{2} + \frac{3}{4} = \frac{5}{4} = 1\frac{1}{4}\]

\[\textbf{б)}\ | - 2,4| - | - 1,9| = 2,4 - 1,9 =\]

\[= 0,5\]

\[\textbf{в)}\ |1,3| + \left| - 2\frac{1}{5} \right| = 1,3 + 2,2 =\]

\[= 3,5\]

\[\textbf{г)}\ | - 2,6| + \left| 3\frac{3}{5} \right| = 2,6 + 3,6 =\]

\[= 6,2\]

\[\textbf{д)}\ \left| - 1\frac{1}{5} \right| \cdot | - 0,6| = 1,2 \cdot 0,6 =\]

\[= 0,72\]

\[\textbf{е)}\ | - 0,7|\ :| - 0,1| = 0,7\ :0,1 = 7\]
