Odpowiedź:
[tex](5 \frac{2}{3} - 3 \frac{6}{7} ) \times ( \frac{1}{2} + \frac{9}{38} ) = (5 \frac{14}{21} - 3 \frac{18}{21} ) \times ( \frac{19}{38} + \frac{9}{38} ) = \\ \\ = (4 \frac{35}{21} - 3 \frac{18}{21} ) \times \frac{28}{38} = 1 \frac{17}{21} \times \frac{28}{38} = \frac{38}{21} \times \frac{28}{38} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
Wynik tego działania to 1 i 1/3
