ГДЗ по математике 5 класс Мерзляк ФГОС Задание 922

\[\boxed{\mathbf{922}.\ }\]

\[1)\ 7\frac{14}{15} + 2\frac{1}{15} = 9\frac{15}{15} = 10\]

\[2)\ 9\frac{24}{27} + 12\frac{13}{27} = 21\frac{37}{27} = 22\frac{10}{27}\]

\[3)\ 1 - \frac{12}{19} = \frac{19 - 12}{19} = \frac{7}{19}\]

\[4)\ 8 - 3\frac{6}{15} = 7\frac{15}{15} - 3\frac{6}{15} = 4\frac{9}{15}\]

\[5)\ 12 - 11\frac{6}{11} = 11\frac{11}{11} - 11\frac{6}{11} =\]

\[= \frac{5}{11}\]

\[6)\ 16\frac{3}{13} - 6\frac{8}{13} =\]

\[= 15\frac{16}{13} - 6\frac{8}{13} = 9\frac{8}{13}\]

\[7)\ 13\frac{4}{9} - 2\frac{8}{9} = 12\frac{13}{9} - 2\frac{8}{9} =\]

\[= 10\frac{5}{9}\]

\[8)\ 10\frac{7}{16} - 4\frac{12}{16} = 9\frac{23}{16} - 4\frac{12}{16} =\]

\[= 5\frac{11}{16}\]

\[9)\ 29\frac{49}{53} - 8\ \frac{49}{53} = 29 - 8 = 21\]
