well, clearly from 248 to 200, it decreased by 48 workers.
if we take 248 to be the 100%, what is 48 off of it in percentage then?
[tex]\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
248&100\\
48&p
\end{array}\implies \cfrac{248}{48}=\cfrac{100}{p}\implies p=\cfrac{48\cdot 100}{248}[/tex]
