\[\textbf{а)}\ \frac{5}{9} = \frac{15}{27} > \frac{4}{27}\]
\[\textbf{б)}\ \frac{7}{24} < \frac{5}{8} = \frac{15}{24}\]
\[\textbf{в)}\ \frac{1}{60} < \frac{13}{30} = \frac{26}{60}\]

\[\frac{1}{2} = \frac{30}{60};\ \frac{2}{6} = \frac{20}{60};\ \frac{5}{10} = \frac{30}{60};\ \]
\[\frac{10}{12} = \frac{50}{60}.\]
\[\frac{2}{6} - наименьшая;\]
\[\frac{10}{12} - наибольшая;\]
\[\frac{1}{2} = \frac{5}{10} - равные.\]
