Answer 2

$\frac{14}{21} \: > \: \frac{8}{21} \:= > \: \frac{2}{3} \: > \: \frac{8}{21}$

$\frac{4}{15} \: < \: \frac{6}{15} \: => \: \frac{4}{15} \: < \: \frac{2}{5}$

$\frac{7}{30} \: < \: \frac{9}{30} \: => \: \frac{7}{30} \: < \: \frac{3}{10}$

$\frac{19}{60} \: > \: \frac{16}{60} \: => \: \frac{19}{60} \: > \: \frac{4}{15}$
