\[1)\ n\ :17 = 4\ 556 + 2\ 445\ \]
\[n\ :17 = 7\ 001\]
\[n = 7\ 001 \cdot 17\]
\[n = 119\ 017.\ \]
\[Ответ:119\ 017.\]
\[2)\ m\ :29 = 3\ 477 - 2\ 963\]
\[m\ :29 = 514\]
\[m = 514 \cdot 29\]
\[m = 14\ 906.\ \]
\[Ответ:14\ 906.\ \]
\[3)\ 140\ 895\ :(z - 197) = 465\]
\[z - 197 = 140\ 895\ :465\]
\[z - 197 = 303\]
\[z = 303 + 197\]
\[z = 500.\]
\[Ответ:500.\ \]
\[4)\ (2\ 747 + x) \cdot 125 = 593\ 375\]
\[2\ 747 + x = 593\ 375\ :125\]
\[2\ 747 + x = 4\ 747\]
\[x = 4\ 747 - 2\ 747\]
\[x = 2\ 000.\]
\[Ответ:2\ 000.\]
