\[\boxed{\ \mathbf{1413}.\ }\]

\[1)\ 50 - (2,3256\ :0,068 + 9,38) =\]

\[= 6,42\]

\[2,3256\ :0,068 = 23\ 256\ :680 =\]

\[= 34,2\]

\[34,2 + 9,38 = 43,58\]

\[50 - 43,58 = 6,42\]

\[6,63\ :0,85 = 663\ :85 =\]

\[3,0752\ :0,62 = 30\ 752\ :6200 =\]

\[= 4,96\]

\[7,8 - 4,96 = 2,84\]

\[40,88 - 4,94 = 35,94\]

\[57,6\ :18 = 3,2\]

\[3,2 + 2,8 = 6\]

\[35,94\ :6 = 3594\ :600 = 5,99\]
