738 : 18 = 41
86 * 9 = 774
Ответ: «машина» делит на 18; умножает на 9.
Вычисления:
$\begin{array}{cc}\begin{array}{l}\underset{¯}{\phantom{0}}738\\ \phantom{0}\underset{¯}{41}\\ \underset{¯}{\phantom{0}}328\\ \phantom{0}\underset{¯}{328}\\ \phantom{000}0\end{array}& \begin{array}{l}\overline{)41}\\ \overline{\overline{)18}}\end{array}\end{array}$
$\begin{array}{cc}\begin{array}{l}\underset{¯}{\phantom{0}}738\\ \phantom{0}\underset{¯}{72}\\ \phantom{0}\underset{¯}{\phantom{0}}18\\ \phantom{00}\underset{¯}{18}\\ \phantom{000}0\end{array}& \begin{array}{l}\overline{)18}\\ \overline{\overline{)41}}\end{array}\end{array}$
