Understanding "Gay-Lussac's law of Gaseous volumes/combining volumes"

Understanding "Gay-Lussac's law of Gaseous volumes/combining volumes". So I was reading Wikipedia and stumble across [this](https://en.wikipedia.org/wiki/Gay-Lussac%27s_law#Law_of_combining_volumes). It defines it as follows "The ratio between the volumes of the reactant gases and the gaseous products can be expressed in simple whole numbers" and then give an example of 
$$\ce{2H2 + O2 -> 2H2O}$$ 
The problem is that example does not fit the definition. The volume of reactants is $3x$ where $x$ is a variable. The volume of product is $2x$. The ratio is $\frac 3 2$, which is not a whole number. Clearly, something is wrong here or something is wrong with me. Either way, can anyone help?

Wikipedia is correct. 


Expressed in, not expressed as.


$3/2$ can be expressed in simple whole numbers $3$ and $2$.
