Szczegółowe wyjaśnienie:
a) [tex]3,4 = 3\frac{4}{10} = 3\frac{4:2}{10:2} = 3\frac{2}{5}[/tex]
b) [tex]0,12 = \frac{12}{100} = \frac{12:2}{100:2}=\frac{6}{50} = \frac{6:2}{50:2}=\frac{3}{25}[/tex]
c) [tex]0,72 = \frac{72}{100} = \frac{72:2}{100:2} = \frac{36}{50} = \frac{36:2}{50:2} = \frac{18}{25}[/tex]
d) [tex]2,55 = 2\frac{55}{100} = 2\frac{55:5}{100:5} = 2\frac{11}{20}[/tex]
e) [tex]0,45 = \frac{45}{100} = \frac{45:5}{100:5} = \frac{9}{20}[/tex]
f) [tex]5,04 = 5\frac{4}{100} = 5\frac{4:4}{100:4} = 5\frac{1}{25}[/tex]
