Odpowiedź:
[tex]\frac{5}{8} + 5\frac{1}{12} = \frac{15}{24} + \frac{122}{24} = \frac{137}{24} \\\\1\frac{3}{8} + 3\frac{3}{4} = (1 + 3) + (\frac{3}{8} + \frac{6}{8}) = 5 \frac{1}{8} \\\\\\\frac{13}{15} - \frac{5}{6} = \frac{26}{30}-\frac{25}{30} = \frac{1}{30} \\\\5 \frac{2}{7} - \frac{11}{3} = \frac{111}{21} - \frac{77}{21} = \frac{34}{21}[/tex]
