Najpierw możemy sobie sprowadzić do wspólnego mianownika.
a)
[tex] \frac{4}{7} = \frac{12}{21} [/tex]
[tex] \frac{2}{3} = \frac{14}{21} [/tex]
Więc
[tex] \frac{4}{7} < \frac{2}{3} [/tex]
b)
[tex] \frac{5}{13} = \frac{15}{39} [/tex]
[tex] \frac{1}{3} = \frac{13}{39} [/tex]
Więc
[tex] \frac{5}{13} > \frac{1}{3} [/tex]
c)
[tex] \frac{3}{7} = \frac{15}{35} [/tex]
[tex] \frac{2}{5} = \frac{14}{35} [/tex]
Więc
[tex] \frac{3}{7} > \frac{2}{5} [/tex]
d)
[tex] \frac{6}{15} = \frac{162}{405} [/tex]
[tex] \frac{25}{27} = \frac{375}{405} [/tex]
Więc
[tex] \frac{6}{15} < \frac{25}{27} [/tex]
e)
[tex]4 \frac{5}{14} = \frac{61}{14} = \frac{122}{28} [/tex]
[tex]4 \frac{10}{28} = \frac{112}{28} [/tex]
Więc
[tex]4 \frac{5}{14} > 4 \frac{10}{28} [/tex]
Myślę że pomogłem ;)
