so.. if we take 427 as the 100%, what is 29%? well [tex]\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
427&100\\
x&29
\end{array}\implies \cfrac{427}{x}=\cfrac{100}{29}[/tex]
solve for "x"
