Advice

Um die Aufgabe zu lösen, kürzen wir die Bruchzahlen.

$\begin{align} \frac{\var{osix}}{\var{psix}}=\frac{\var{o_coprime}}{\var{p_coprime}}\times\frac{\var{six}}{\var{six}} \\[0.5em] \frac{\var{oseven}}{\var{pseven}}=\frac{\var{o_coprime}}{\var{p_coprime}}\times\frac{\var{seven}}{\var{seven}} \\[0.5em] \frac{\var{oeight}}{\var{peight}}=\displaystyle\frac{\var{o_coprime}}{\var{p_coprime}}\times\frac{\var{eight}}{\var{eight}} \\[0.5em] \frac{\var{onine}}{\var{pnine}}=\frac{\var{o_coprime}}{\var{p_coprime}}\times\frac{\var{nine}}{\var{nine}} \\[0.5em] \frac{\var{oten}}{\var{pten}} = \frac{\var{oten/gcd(oten,pten)}}{\var{pten/gcd(oten,pten)}} \times \frac{\var{gcd(oten,pten)}}{\var{gcd(oten,pten)}} \end{align}$

Der gesuchte Bruch ist $\displaystyle\frac{\var{oten}}{\var{pten}}$ .
