\begin{gathered} 1\colon3=(1)/(3) \\ 9\colon27=(9)/(27) \\ so\colon \\ (9)/(27)=(3)/(3)*((1)/(3)) \end{gathered}
\begin{gathered} 81\colon9=(81)/(9) \\ 9\colon1=(9)/(1) \\ so\colon \\ (81)/(9)=(9)/(9)*((9)/(1)) \end{gathered}

According to the above, we can conclude that when one player names a ratio, the other must answer with an equivalent ratio. Therefore, for a given ratio:


\begin{gathered} a\colon b=(a)/(b) \\ b\\e0 \end{gathered}

The answer from the other player must be given by:


\begin{gathered} ka\colon kb=(k)/(k)*(a)/(b)=(ka)/(kb) \\ k\in N \end{gathered}
