ГДЗ по математике 6 класс Мерзляк ФГОС Задание 360

\[\boxed{\mathbf{360}\mathbf{.}}\]

\[1)\ \frac{1}{7}x = \frac{5}{6}\]

\[x = \frac{5}{6}\ :\frac{1}{7}\]

\[x = \frac{5}{6} \cdot 7\]

\[x = \frac{35}{6}\]

\[x = 5\frac{5}{6}.\]

\[2)\ \frac{4}{15}\ :x = 8\]

\[x = \frac{4}{15}\ :8\]

\[x = \frac{4}{15} \cdot \frac{1}{8}\]

\[x = \frac{1}{30}.\]

\[3)\ 1\frac{4}{9}x = 5\frac{1}{5}\]

\[x = \frac{26}{5}\ :\frac{13}{9}\]

\[x = \frac{26}{5} \cdot \frac{9}{13}\]

\[x = \frac{26 \cdot 9}{5 \cdot 13}\]

\[x = \frac{18}{5}\]

\[x = 3\frac{3}{5}.\]
