Answer 1

$\frac{5}{7}\ \textgreater \ \frac{2}{7} \\ \\ \frac{3}{11}= \frac{12}{44} \\ \frac{3}{4}= \frac{33}{44} \\ =\ \textgreater \ \frac{3}{11}\ \textless \ \frac{3}{4} \\ \\ 0.5= \frac{5}{10}= \frac{1}{2} \\ =\ \textgreater \ \frac{1}{2}=0.5 \\ \\ 0.25= \frac{25}{100}= \frac{5}{20}= \frac{1}{4} \\ =\ \textgreater \ 0.25= \frac{1}{4}$
