Answer 1

1)$\frac{7}{10}= \frac{14}{20} ; \frac{14}{20}\ \textgreater \ \frac{13}{20}; \frac{7}{10}\ \textgreater \ \frac{13}{20}$
2)$\frac{2}{3}= \frac{16}{24}; \frac{5}{8}= \frac{15}{24}; \frac{16}{24}\ \textgreater \ \frac{15}{24}; \frac{2}{3}\ \textgreater \ \frac{5}{8}$
3)$\frac{7}{10}= \frac{14}{20}; \frac{3}{4}= \frac{15}{20}; \frac{14}{20}\ \textless \ \frac{15}{20}; \frac{7}{10}\ \textless \ \frac{3}{4}$
4)$\frac{7}{9}= \frac{14}{18}; \frac{5}{6}= \frac{15}{18}; \frac{14}{18}\ \textless \ \frac{15}{18}; \frac{7}{9}\ \textless \ \frac{5}{6}$
5)$\frac{7}{15}= \frac{28}{60}; \frac{9}{20}= \frac{27}{60}; \frac{28}{60}\ \textgreater \ \frac{27}{60}; \frac{7}{15}\ \textgreater \ \frac{9}{20}$
