Решебник по математике 6 класс Мерзляк ФГОС Задание 338

\[\boxed{\mathbf{338\ (338).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\boxed{\mathbf{338}\mathbf{.}}\]

\[1)\ x - 4\frac{5}{8} = 7\frac{17}{32}\]

\[x = 7\frac{17}{32} + 4\frac{5^{\backslash 4}}{8}\]

\[x = 7\frac{17}{32} + 4\frac{20}{32}\]

\[x = 11\frac{37}{32}\]

\[x = 12\frac{5}{32}.\]

\[2)\ x + \frac{8}{9} = 1\frac{7}{12}\]

\[x = 1\frac{7^{\backslash 3}}{12} - \frac{8^{\backslash 4}}{9}\]

\[x = 1\frac{21}{36} - \frac{32}{36} = \frac{57}{36} - \frac{32}{36}\]

\[x = \frac{25}{36}.\]

\[3)\ 3\frac{1}{6} - x = \frac{5}{18}\]

\[x = 3\frac{1^{\backslash 3}}{6} - \frac{5}{18}\]

\[x = 3\frac{3}{18} - \frac{5}{18}\]

\[x = 2\frac{21}{18} - \frac{5}{18}\]

\[x = 2\frac{16}{18} = 2\frac{8}{9}.\]
