that numbers is hmmm "x"
so.. for that matter, "x" is 100% then, and 188 is just the 67%
thus [tex]\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
x&100\\
188&67
\end{array}\implies \cfrac{x}{188}=\cfrac{100}{67}[/tex]
