\[\boxed{\mathbf{551\ (551).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 1\ :9 = 0,(1)\]

\[2)\ 4\ :11 = 0,(36)\]

\[3)\ 47\ :12 = 3,91(6)\]

\[4)\ 12,4\ :27 = 0,4(592)\]

\[\boxed{\mathbf{551.}\mathbf{\ }}\]

\[1)\ (6 + 14)\ :2 = 20\ :2 = 10\]

\[2)\ (10 + 15)\ :2 = 25\ :2 = 12,5\]

\[3)\ (7 + 9 + 14)\ :3 =\]

\[= 30\ :3 = 10\]

\[4)\ (2 + 3 + 4 + 5)\ :4 =\]

\[= 14\ :4 = 3,5\]
