\[\boxed{\text{220\ (220).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
Пояснение.
Решение.
\[1)\ 8 \cdot 8 + 6 = 64 + 6 = 70\]
\[70\ :8 = 8\ (ост.\ 6)\]
\[2)\ 106 \cdot 7 + 5 = 742 + 5 = 747\]
\[747\ :7 = 106\ (ост.\ 5)\]
\[3)\ 2 \cdot 30 + 20 = 60 + 20 = 80\]
\[80\ :30 = 2\ (ост.\ 20)\]
\[4)\ 1 \cdot 57 + 2 = 59\]
\[59\ :57 = 1\ (ост.\ 2)\]
