Сравните дроби:
1) $\frac{5}{7}$ и $\frac{7}{9}$;
2) $\frac{11}{20}$ и $\frac{17}{30}$;
3) $\frac{2}{9}$ и $\frac{1}{6}$;
4) $\frac{5}{6}$ и $\frac{3}{4}$;
5) $\frac{8}{38}$ и $\frac{4}{19}$;
6) $\frac{7}{9}$ и $\frac{8}{11}$;
7) $\frac{8}{25}$ и $\frac{7}{20}$;
8) $\frac{5}{12}$ и $\frac{4}{9}$.
$\frac{5}{7} = \frac{45}{63}$ < $\frac{7}{9} = \frac{49}{63}$
$\frac{11}{20} = \frac{33}{60}$ < $\frac{17}{30} = \frac{34}{60}$
$\frac{2}{9} = \frac{4}{18}$ > $\frac{1}{6} = \frac{3}{18}$
$\frac{5}{6} = \frac{10}{12}$ > $\frac{3}{4} = \frac{9}{12}$
$\frac{8}{38}$ = $\frac{4}{19} = \frac{8}{38}$
$\frac{7}{9} = \frac{77}{99}$ > $\frac{8}{11} = \frac{72}{99}$
$\frac{8}{25} = \frac{32}{100}$ < $\frac{7}{20} = \frac{35}{100}$
$\frac{5}{12} = \frac{15}{36}$ < $\frac{4}{9} = \frac{16}{36}$
