a)
[tex] \frac{7}{9} i\frac{2}{3} = \frac{7}{9} i \frac{6}{9} \\ \\ \frac{7}{9} > \frac{2}{3} [/tex]
b)
[tex] \frac{2}{7} i \frac{3}{14} = \frac{4}{14} i \frac{3}{14} \\ \\ \frac{2}{7} > \frac{3}{14} [/tex]
c)
[tex] \frac{9}{32} i \frac{3}{8} = \frac{9}{32} i \frac{12}{32} \\ \\ \frac{9}{32} < \frac{3}{8} [/tex]
d)
[tex] \frac{7}{9} i \frac{53}{81} = \frac{63}{81} i \frac{53}{81} \\ \\ \frac{7}{9} > \frac{53}{81} [/tex]
Myślę że pomogłem ;)
