\[\boxed{\mathbf{1014\ (1005)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 16 - 29 + 14 - 48 = 30 -\]

\[- 77 = - 47\]

\[2) - 3,2 - 7,8 - 5,4 + 4,6 =\]

\[= 4,6 - 16,4 = - 11,8\]

\[3) - 4,28 - 1,53 - ( - 7,85) +\]

\[+ ( - 9,06) = - 5,81 +\]

\[+ 7,85 - 9,06 =\]

\[= 7,85 - 14,87 = - 7,02\]

\[4) - 5\frac{3}{8} + 4\frac{5}{6} - \left( - 2\frac{1}{4} \right) =\]

\[= - 5\frac{9}{24} + 4\frac{20}{24} + 2\frac{6}{24} =\]

\[= 6\frac{26}{24} - 5\frac{9}{24} = 1\frac{17}{24}\]

\[5) - 3\frac{3}{5} + \left( - 2\frac{1}{3} \right) + 4\frac{8}{15} -\]

\[- 1\frac{5}{6} - \left( - 6\frac{7}{10} \right) + \frac{1}{2} =\]

\[= - 3\frac{18}{30} - 2\frac{10}{30} + 4\frac{16}{30} - 1\frac{25}{30} +\]

\[+ 6\frac{21}{30} + \frac{15}{30} =\]

\[= 10\frac{52}{30} - 6\frac{53}{30} = 3\frac{29}{30}\]
