Решение:
- \( 0,5 = \frac{5}{10} = \frac{1}{2} \)
- \( 0,75 = \frac{75}{100} = \frac{3}{4} \)
- \( 0,4 = \frac{4}{10} = \frac{2}{5} \)
- \( 0,35 = \frac{35}{100} = \frac{7}{20} \)
- \( 0,12 = \frac{12}{100} = \frac{3}{25} \)
- \( 0,625 = \frac{625}{1000} = \frac{5}{8} \)
- \( 0,08 = \frac{8}{100} = \frac{2}{25} \)
- \( 0,875 = \frac{875}{1000} = \frac{7}{8} \)
- \( 0,045 = \frac{45}{1000} = \frac{9}{200} \)
- \( 0,225 = \frac{225}{1000} = \frac{9}{40} \)
