\[\boxed{\mathbf{2.}\mathbf{136}}\]

\[\textbf{а)}\ \frac{3}{4} = \frac{3 \cdot 25}{4 \cdot 25} = \frac{75}{100} = 0,75\]

\[\frac{7}{50} = \frac{14}{100} = 0,14\]

\[\frac{13}{25} = \frac{13 \cdot 4}{25 \cdot 4} = \frac{52}{100} = 0,42\]

\[\frac{1}{8} = \frac{125}{1000} = 0,125\]

\[\frac{17}{250} = \frac{17 \cdot 4}{250 \cdot 4} = \frac{68}{1000} = 0,068\]

\[\frac{101}{200} = \frac{101 \cdot 5}{200 \cdot 5} = \frac{505}{1000} = 0,505\]

\[\textbf{б)}\ 0,3 = \frac{3}{10}\]

\[0,5 = \frac{5}{10} = \frac{1}{2}\]

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

\[0,28 = \frac{28}{100} = \frac{7}{25}\]

\[0,45 = \frac{45}{100} = \frac{9}{20}\]

\[0,80 = \frac{8}{10} = \frac{4}{5}\]

\[0,04 = \frac{4}{100} = \frac{1}{25}\]

\[0,125 = \frac{125}{1000} = \frac{1}{8}\]

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

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

\[0,765 = \frac{765}{1000} = \frac{153}{500}\]
