Question

помогите пожалуйста ​

Answer 1

Ответ:

1.

$1) \frac{7}{8} > \frac{5}{8} \\\\2) \frac{9}{11} > \frac{2}{11}\\\\3) \frac{3}{4} < \frac{7}{8}\\\\4) \frac{7}{10} > \frac{8}{15}$

2.

$1) \frac{2}{9} + \frac{4}{9} = \frac{6}{9} = \frac{2}{3} \\\\2) \frac{12}{23} - \frac{9}{23} = \frac{3}{23}\\\\3) \frac{5}{12} + \frac{1}{6} = \frac{5}{12} + \frac{2}{12} = \frac{7}{12}\\\\4) \frac{9}{14} - \frac{2}{21} = \frac{27}{42} - \frac{4}{42} = \frac{23}{42}$
