\[\boxed{\text{212\ (212).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
Пояснение.
Решение.
\[1)\ 73\ :8 = 9\ (ост.\ 1)\ \]
\[79\ :8 = 9\ \ (ост.\ 7)\]
\[36\ :7 = 5\ (ост.1)\]
\[41\ :7 = 5\ (ост.\ 6)\]
\[81\ :20 = 4\ (ост.1)\]
\[99\ :20 = 4\ (ост.19)\]
\[61\ :30 = 2\ (ост.1)\]
\[89\ :30 = 2\ (ост.29)\]
\[2\ :9 = 0\ (ост.2)\]
\[7\ :8 = 0\ (ост.7)\]
\[2)\ 989\ :3 = 329\ (ост.\ 2)\]
\[549\ :5 = 109\ (ост.\ 4)\]
\[351\ :4 = 87\ (ост.\ 3)\]
\[629\ :6 = 104\ (ост.\ 5)\]
\[5\ :6 = 0\ (ост.\ 5)\]
