Odpowiedź:
[tex]a) \frac{1}{3} + 0,25 = \frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}[/tex]
[tex]b) 0,75 - \frac{4}{7} = \frac{3}{4} - \frac{4}{7} = \frac{21}{28} - \frac{16}{28} = \frac{5}{28}[/tex]
[tex]c) 4\frac{1}{3} : 0,26 = 4\frac{1}{3} : \frac{26}{100} = \frac{13}{3} : \frac{26}{100} = \frac{13}{3} * \frac{100}{26} = \frac{1}{3} * \frac{100}{2} = \frac{100}{6} = 16 \frac{4}{6} = 16\frac{2}{3}[/tex]
[tex]d) 3,6 * 1\frac{7}{9} = 3\frac{6}{10} * 1\frac{7}{9} = \frac{36}{10} * \frac{16}{9} = \frac{4}{5} * \frac{8}{1} = \frac{32}{5} = 6\frac{2}{5}[/tex]
