ГДЗ по математике 6 класс Мерзляк ФГОС Задание 543

\[\boxed{\mathbf{5}\mathbf{43}}\]

\[1)\ 9x = 5\]

\[x = 5\ :9\]

\[x = 0,(5)\]

\[x \approx 0,56.\]

\[2)\ 8\ :x = 125\]

\[x = 8\ :125\]

\[x = 0,064\]

\[x \approx 0,06.\]

\[3)\ 3x = 4\]

\[x = 4\ :3\]

\[x = 1,(3)\]

\[x \approx 1,33.\]

\[4)\ \frac{2}{7}x = 1\frac{1}{6}\]

\[x = \frac{7}{6}\ :\frac{2}{7}\]

\[x = \frac{7 \cdot 7}{6 \cdot 2}\]

\[x = \frac{49}{12}\]

\[x = 4,08(3)\]

\[x \approx 4,08.\]
