\[\boxed{\mathbf{1238}\mathbf{.}}\]
\[x - данное\ числож\]
\[a - целая\ часть\ при\ первом\ \]
\[делении.\]
\[\frac{x - 68}{72} = a\]
\[x - 68 = 72a\]
\[x = 72a + 68.\]
\[2)\ Остаток\ при\ делении\ на\ 12:\]
\[\frac{x}{12} = \frac{72a + 68}{12} =\]
\[= \frac{12 \bullet 6a + (12 \bullet 5 + 8)}{12} =\]
\[= \frac{12(6a + 5) + 8}{12}.\]
\[Ответ:\ \ 8.\]
