[tex]a) \: 0.6 = \frac{6}{10} = \frac{3}{5} \\ 0.9 = \frac{9}{10 } \\ b) \: 0.50 = \frac{5}{10} = \frac{1}{2} \\ 0.75 = \frac{75}{100} = \frac{3}{4} \\ c) \: 0.125 = \frac{125}{1000} = \frac{1}{8} \\ 0.085 = \frac{85}{1000} = \frac{17}{200} [/tex]

[tex] \frac{1}{2} = \frac{5}{10} = 0.5 \\ \frac{2}{5} = \frac{4}{10} = 0.4 \\ \frac{13}{50} = \frac{26}{100} = 0.26 \\ \frac{7}{25} = \frac{28}{100} = 0.28[/tex]
Mam nadzieję, że pomogłam :)
