The points \(S\), \(Y\), \(N\), \(C\), \(R\), \(A\), \(T\), \(I\) and \(O\) on the number line are such that \(CN = NY = YS\) and \(RA = AT = TI = IO\). Find the rational numbers represented by the letters \(Y\), \(N\), \(A\), \(T\) and \(I\).

 

 

$Y=\frac{i}{i}$, $N=\frac{i}{i}$, $A=\frac{i}{i}$, $T=\frac{i}{i}$, $T=\frac{i}{i}$
