Answer 1

$\frac{2}{13}< \frac{15}{16}; \frac{2}{13}= \frac{32}{208}; \frac{15}{16}= \frac{195}{208}\\ \frac{7}{21}< \frac{51}{64}; \frac{7}{21}= \frac{1}{3}= \frac{64}{192}; \frac{51}{64}= \frac{153}{192} \\ \frac{51}{100}> \frac{54}{110}; \frac{51}{100}= \frac{561}{1100}; \frac{54}{110}= \frac{540}{1100}\\ \frac{3}{4}> \frac{62}{125}; \frac{3}{4}= \frac{375}{500}; \frac{62}{125}= \frac{248}{500}$
