Szczegółowe wyjaśnienie:
0,32 + 1,2 = 1,52 = [tex]1\frac{52}{100} = 1\frac{26}{50} = 1\frac{13}{25}[/tex]
2,04 - 1,2 = 0,84 = [tex]\frac{84}{100} = \frac{42}{50} = \frac{21}{25}[/tex]
[tex]\frac{5}{8} * 1\frac{4}{5} = \frac{5}{8} * \frac{9}{5} = \frac{1}{8} * 9 = \frac{9}{8} = 1\frac{1}{8}[/tex]
[tex]\frac{16}{10} : \frac{4}{5} = \frac{16}{10} * \frac{5}{4} = \frac{4}{2} * 1 = 2* 1 = 2[/tex]
