\[\boxed{\text{5.\ 23}}\]

\[\textbf{а)}\ \frac{2}{5} = 0,4\]

\[4\frac{1}{2} = 4,5\]

\[\frac{3}{4} = \frac{75}{100} = 0,75\]

\[5\frac{7}{20} = 5\frac{35}{100} = 5,35\]

\[1\frac{5}{8} = 1\frac{625}{1000} = 1,625\]

\[\textbf{б)}\ 2,4 = \frac{24}{10} = \frac{12}{5}\]

\[4,5 = \frac{45}{10} = \frac{9}{2}\]

\[0,25 = \frac{25}{100} = \frac{1}{4}\]

\[2,55 = \frac{255}{100} = \frac{51}{20}\]

\[6,625 = \frac{6625}{1000} = \frac{265}{40} = \frac{53}{8}\]
