a. $\frac{3}{10}$ < $\frac{7}{10}$ $\frac{5}{8}$ > $\frac{3}{8}$ $\frac{25}{31}$ > $\frac{19}{31}$
b. $\frac{7}{8}$ ... $\frac{5}{6}$ $\frac{2}{5}$ ... $\frac{3}{7}$ $\frac{1}{4}$ ... $\frac{1}{6}$
=>$\frac{21}{24}$ > $\frac{20}{24}$ =>$\frac{14}{35}$ < $\frac{15}{35}$ =>$\frac{3}{12}$ > $\frac{2}{12}$
c. $\frac{2}{5}$ .... 1 $\frac{7}{6}$ ... 1 $\frac{21}{21}$ .... 1
=>$\frac{2}{5}$ < $\frac{5}{5}$ => $\frac{7}{6}$ > $\frac{6}{6}$ => 1 = 1
d. $\frac{7}{6}$ < $\frac{7}{3}$ $\frac{12}{17}$ < $\frac{12}{13}$ $\frac{2}{3}$ > $\frac{2}{5}$
