9. Вставить пропущенные числа. * \(\square \cdot 2 = 80\) * \(44: \square = 44\) * \(\square : 12 = 4\) * \(60: \square = 15\) * \(\square \cdot 8 = 88\) * \(14 \cdot \square = 42\)

Решаем уравнения: * \(\square \cdot 2 = 80\) \(\Rightarrow\) \(\square = 80 \div 2 = 40\) * \(44: \square = 44\) \(\Rightarrow\) \(\square = 44 \div 44 = 1\) * \(\square : 12 = 4\) \(\Rightarrow\) \(\square = 4 \cdot 12 = 48\) * \(60: \square = 15\) \(\Rightarrow\) \(\square = 60 \div 15 = 4\) * \(\square \cdot 8 = 88\) \(\Rightarrow\) \(\square = 88 \div 8 = 11\) * \(14 \cdot \square = 42\) \(\Rightarrow\) \(\square = 42 \div 14 = 3\) Ответ: 40, 1, 48, 4, 11, 3
