Answer: the ratio of red cars to green cars to Blue cars

 5 :6: 20

The ratio of red cars, green cars and blue cars is \(\boxed{\bf 5:6:20}\).


Further explanation:

The ratio of red car to the green cars in a car parking is \(5:6\).

Consider \(C_{r}\) as the number of red cars and \(C_{g}\) as the number of green cars.

The ratio of red car to the green cars can be expressed as follows:

\(\boxed{C_{r}:C_{g}=5:6}\)  

The ratio \(C_{r}:C_{g}=5:6\) can also be written as follows:

\(\begin{aligned}\dfrac{C_{r}}{C_{g}}&=\dfrac{5}{6}\\C_{r}&=\dfrac{5}{6}C_{g}\end{aligned}\)

The ratio of green cars to the blue cars is \(3:10\).

Consider \(C_{b}\) as the number of blue cars.

The ratio of green cars to the blue cars can be expressed as follows:

\(\boxed{C_{g}:C_{b}=3:10}\)

The ratio \(C_{g}:C_{b}=3:10\) can also be written as follows:

\(\begin{aligned}\dfrac{C_{g}}{C_{b}}&=\dfrac{3}{10}\\C_{g}&=\dfrac{3}{10}C_{b}\end{aligned}\)

The ratio of red cars, green cars and blue cars can be expresses as \(\boxed{C_{r}:C_{g}:C_{b}}\).

Substitute \(C_{r}=\frac{5}{6}C_{g}\) and \(C_{b}=\frac{10}{3}C_{g}\) in the ratio \(C_{r}:C_{g}:C_{b}\) as follows:

\(\begin{aligned}C_{r}:C_{g}:C_{b}&=\dfrac{5}{6}C_{g}:C_{g}:\dfrac{10}{3}C_{g}\\&=\dfrac{5}{6}:1:\dfrac{10}{3}\\&=5:6:(2\cdot 10)\\&=5:6:20\end{aligned}\)

The ratio of red cars, green cars and blue cars is \(5:6:20\).

Thus, the ratio of red cars, green cars and blue cars is \(\boxed{\bf 5:6:20}\).
