[tex] \frac{19}{7} \\ 3 \frac{1}{7} = \frac{22}{7} \\ \\ \frac{19}{7} < 3 \frac{1}{7} [/tex]
b)
Prawda
[tex] \frac{7}{16} = \frac{14}{32} \\ \frac{13}{32} \\ \\ \frac{7}{16} > \frac{13}{32} [/tex]
c)
Fałsz
[tex] \frac{18}{36} = \frac{684}{1368} \\ \frac{17}{38} = \frac{612}{1368} \\ \\ \frac{18}{36} > \frac{17}{38} [/tex]
d)
Fałsz
[tex] \frac{3}{5} = \frac{21}{35} \\ \frac{3}{7} = \frac{15}{35} \\ \\ \frac{3}{5} > \frac{3}{7} [/tex]
