ГДЗ по математике 5 класс Мерзляк Задание 776

\[\boxed{\mathbf{776\ (776)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ \frac{14}{93} + 5 = 5\frac{14}{93}\]

\[2)\ 6\frac{17}{41} + 7\frac{19}{41} =\]

\[= (6 + 7) + \left( \frac{17}{41} + \frac{19}{41} \right) =\]

\[= 13 + \frac{36}{41} = 13\frac{36}{41}\]

\[3)\ 24\frac{9}{38} - 17\frac{5}{38} =\]

\[= (24 - 17) + \left( \frac{9}{38} - \frac{5}{38} \right) =\]

\[= 7 + \frac{4}{38} = 7\frac{4}{38}\]

\[4)\ 15\frac{7}{10} - 2\frac{4}{10} + 6\frac{1}{10} =\]

\[= 19 + \frac{4}{10} = 19\frac{4}{10}\]
