ГДЗ по математике 5 класс Мерзляк ФГОС Задание 974

\[\boxed{\ \mathbf{974\ (974)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ \frac{1}{2} = 0,5\]

\[2)\ \frac{5}{8} = 0,625\]

\[3)\ \frac{19}{25} = 0,76\]

\[4)\frac{19}{8} = 2,375\]

\[5)\frac{47}{200} = 0,235\]

\[\boxed{\mathbf{974}\mathbf{.}\mathbf{\ }}\]

\[\frac{2 \cdot 2}{y \cdot 2} = \frac{4}{2y}\text{\ \ \ \ \ \ }\]

\[\frac{4}{2y} = \frac{x}{6}\text{\ \ }\]

\[x = 4.\ \ \ \ \ \ \]

\[2y = 6\]

\[y = 6\ :2\]

\[y = 3.\]

\[Ответ:x = 4;\ \ y = 3.\]
