\[\boxed{\mathbf{1.}}\]

\[\frac{6}{24} = \frac{1}{4}\]

\[\frac{12}{24} = \frac{1}{2}\]

\[\frac{9}{24} = \frac{3}{8}\]

\[\frac{16}{24} = \frac{2}{3}\]

\[\boxed{\mathbf{2.}}\]

\[\frac{16}{20} = \frac{4}{5}\]

\[\frac{12}{18} = \frac{2}{3}\]

\[\frac{10}{15} = \frac{2}{3}\]

\[\frac{9}{15} = \frac{3}{5}\]

\[\frac{25}{15} = \frac{5}{3}\]

\[\boxed{\mathbf{3.}}\]

\[\frac{1}{7} = \frac{2}{14} = \frac{3}{21} = \frac{4}{28}\]

\[\boxed{\mathbf{4.}}\]
