Answer 1

$\frac{10}{21} > \frac{8}{21} \\ \frac{8}{19} < \frac{8}{9} \\ \frac{4}{7} < 1 = \frac{7}{7} \\ \frac{7}{4} = 1 \frac{3}{4} > 1 \\ \\ 1 = \frac{15}{15} > \frac{11}{15} \\ 1> \frac{11}{15} < \frac{15}{11} = 1 \frac{4}{11} > 1 \\ 2 = \frac{6}{3} > \frac{5}{3} \\ 2 = { \frac{6}{3} } < \frac{7}{3} = 2 \frac{1}{3}$
