1.\(\left(\frac{-10}{15}+1\frac{1}{6}-0,5\right):\left(4\frac{4}{105}-5\frac{4}{81}\right)\)

=\(\left(\frac{-10}{15}+\frac{7}{6}-0,5\right):\left(\frac{425}{105}-\frac{409}{81}\right)\)

=\(0:\left(\frac{425}{105}-\frac{409}{81}\right)\)

=\(0\)

2. \(\frac{1}{2}\left(\frac{-11}{19}\right)-50\%.\left(\frac{-1}{19}\right)+\frac{10}{19}.\frac{1111}{2222}\)

=\(\frac{-11}{38}-\frac{-1}{38}+\frac{5}{19}\)

=\(\frac{-11}{38}+\frac{1}{38}+\frac{5}{19}\)

=\(0\)
