Odpowiedź:
a)
[tex]\frac{2}{3} = \frac{14}{21}[/tex]
[tex]\frac{6}{7} = \frac{18}{21}[/tex]
[tex]\frac{14}{21} < \frac{18}{21}[/tex]
[tex]\frac{2}{3} < \frac{6}{7}[/tex]
b)
[tex]\frac{3}{4} = \frac{15}{20}[/tex]
[tex]\frac{4}{5} = \frac{16}{20}[/tex]
[tex]\frac{15}{20} < \frac{16}{20}[/tex]
[tex]\frac{3}{4} < \frac{4}{5}[/tex]
c)
[tex]\frac{5}{8} = \frac{25}{40}[/tex]
[tex]\frac{3}{5} = \frac{24}{40}[/tex]
[tex]\frac{25}{40} > \frac{24}{40}[/tex]
[tex]\frac{5}{8} > \frac{3}{5}[/tex]
d)
[tex]\frac{7}{11} = \frac{21}{33}[/tex]
[tex]\frac{2}{3} = \frac{22}{33}[/tex]
[tex]\frac{21}{33} < \frac{22}{33}[/tex]
[tex]\frac{7}{11} < \frac{2}{3}[/tex]
