\[\boxed{\mathbf{1022\ (1022)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 65,8\ :0,28 = 6580\ :28 =\]

\[= 235 - уменьшаемое.\]

\[2)\ 235 - 65,8 =\]

\[= 169,2 - разность.\]

\[Ответ:169,2.\]

\[\boxed{\mathbf{1022}\mathbf{.}\mathbf{\ }}\]

\[1)\ 6\frac{3}{11} + x = 10\frac{6}{7}\text{\ \ }\]

\[x = 10\frac{6^{\backslash 11}}{7} - 6\frac{3^{\backslash 7}}{11}\]

\[x = 10\frac{66}{77} - 6\frac{21}{77}\]

\[x = 4\frac{45}{77}\]

\[Ответ:4\frac{45}{77}.\]

\[2)\ 9\frac{5}{36} - x = 2\frac{4}{9}\text{\ \ \ \ \ }\]

\[x = 9\frac{5}{36} - 2\frac{4^{\backslash 4}}{9}\]

\[x = 8\frac{41}{36} - 2\frac{16}{36}\]

\[x = 6\frac{25}{36}\]

\[Ответ:6\frac{25}{36}.\]

\[3)\ x - 5\frac{17}{60} = 7\frac{9}{20}\text{\ \ \ }\]

\[x = 7\frac{9^{\backslash 3}}{20} + 5\frac{17}{60}\]

\[x = 7\frac{27}{60} + 5\frac{17}{60}\]

\[x = 12\frac{44}{60} = 12\frac{11}{15}\]

\[Ответ:12\frac{11}{15}.\]
