Answer 2

Ответ:

$1)7 \frac{14}{15} + 2 \frac{1}{15} = 10 \\ 2)9 \frac{24}{27} + 12 \frac{13}{27} = 21 \frac{37}{27} = 22 \frac{10}{27} \\ 3)1 - \frac{12}{19} = \frac{7}{19} \\ 4)8 - 3 \frac{6}{15} = 5 - \frac{6}{15} = 4 \frac{9}{15}$

$5)12 - 11 \frac{6}{11} = \frac{5}{11}$

$6)16 \frac{3}{13} - 6 \frac{8}{13} = 10 \frac{3}{13} - \frac{8}{13} = 9 \frac{16}{13} - \frac{8}{13} = 9 \frac{8}{13} \\ 7)13 \frac{4}{9} - 2 \frac{8}{9} = 10 \frac{13}{9} - \frac{8}{9} = 10 \frac{5}{9} \\ 8)10 \frac{7}{16} - 4 \frac{12}{16} = 5 \frac{23}{16} - \frac{12}{16} = 5 \frac{11}{16} \\ 9)29 \frac{49}{53} - 8 \frac{49}{53} = 21$

$10)(20 \frac{16}{25} + 13 \frac{9}{25} ) - (23 \frac{4}{14} + 7 \frac{13}{14} ) = 33 \frac{25}{25} - 30 \frac{17}{14} = 34 - 31 \frac{3}{14} = 2 \frac{11}{14}$
