Writing a sentence as a proportion I tried to write the following sentence as a proportion: 
6 printers is to 24 computers as 2 printers is to 6 computers: 
${6\,\,printers\over 2\,\,printers} = {24\,\,computers\over 6\,\,computers} $
But when I try to check if the statement is true, it is not. Therefore, it's not a proportion. 

So what is the right way to write this? 


If you need $6$ printers to $24$ computers so $2$ printers for $\color{blue}8$ computers
$$\frac{24}{6}=\frac{8}{2}$$
$$\frac{24}{6}\color{red}\neq\frac{6}{2}$$
$\Longrightarrow1$ printer for $4$ computers, so if you have $6$ computers so you need $2$ printers
