12) 3\(\frac{2}{5}\) \(\cdot\) \(\frac{1}{34}\) =
Ответ:
Решение:
Преобразуем смешанное число в неправильную дробь:
- \(3\frac{2}{5} = \frac{3 \cdot 5 + 2}{5} = \frac{17}{5}\)
Перемножим дроби:
\[ \frac{17}{5} \cdot \frac{1}{34} = \frac{17 \cdot 1}{5 \cdot 34} = \frac{1}{5 \cdot 2} = \frac{1}{10} \]
Ответ: \(\frac{1}{10}\)
