Answer 1

Пошаговое объяснение:

1)

$\frac{5}{9} + \frac{13}{27} = \frac{15}{27} + \frac{13}{27} = \frac{28}{27} = 1 \frac{1}{27}$

2)

$\frac{3}{8} + \frac{5}{24} = \frac{9}{24} + \frac{5}{24} = \frac{14}{24} = \frac{7}{12}$

3)

$\frac{5}{12} - \frac{13}{72} = \frac{30}{72} - \frac{13}{72} = \frac{17}{72}$

4)

$\frac{3}{5} - \frac{1}{7} = \frac{21}{35} - \frac{5}{35} = \frac{16}{35}$

5)

$\frac{5}{12} + \frac{1}{60} = \frac{25}{60} + \frac{1}{60} = \frac{26}{60} = \frac{13}{30}$

6)

$\frac{9}{17} - \frac{19}{68} = \frac{36}{68} - \frac{19}{68} = \frac{17}{68} = \frac{1}{4}$

7)

$\frac{9}{10} + \frac{4}{15} = \frac{27}{30} + \frac{8}{30} = \frac{35}{30} = \frac{7}{6} = 1 \frac{1}{6}$

8)

$\frac{4}{15} - \frac{11}{60} = \frac{16}{60} - \frac{11}{60} = \frac{5}{60} = \frac{1}{12}$
