Ответ:

а) \( 5\frac{3}{10} = 5,3 \)

\( 7\frac{4}{10} = 7,4 \)

\( 13\frac{13}{100} = 13,13 \)

\( 8\frac{21}{100} = 8,21 \)

\( 9\frac{8}{100} = 9,08 \)

\( 100\frac{1}{100} = 100,01 \)

\( 303\frac{303}{1000} = 303,303 \)

\( 12\frac{25}{1000} = 12,025 \)

б) \( 324\frac{7}{1000} = 324,007 \)

\( 9\frac{19}{10\,000} = 9,0019 \)

\( 21\frac{407}{100\,000} = 21,00407 \)

\( 320\frac{1}{10\,000} = 320,0001 \)

\( \frac{8}{10} = 0,8 \)

\( \frac{9}{100} = 0,09 \)

\( \frac{1}{100\,000} = 0,00001 \)
