Divide both sides by \(91050\).
\[\frac{1}{91050}=NDN\times 36900\]
Regroup terms.
\[\frac{1}{91050}=36900DNN\]
Divide both sides by \(36900\).
\[\frac{\frac{1}{91050}}{36900}=DNN\]
Simplify \(\frac{\frac{1}{91050}}{36900}\) to \(\frac{1}{91050\times 36900}\).
\[\frac{1}{91050\times 36900}=DNN\]
Simplify \(91050\times 36900\) to \(3359745000\).
\[\frac{1}{3359745000}=DNN\]
Divide both sides by \(DN\).
\[\frac{\frac{1}{3359745000}}{DN}=N\]
Simplify \(\frac{\frac{1}{3359745000}}{DN}\) to \(\frac{1}{3359745000DN}\).
\[\frac{1}{3359745000DN}=N\]
Switch sides.
\[N=\frac{1}{3359745000DN}\]
N=1/(3359745000*DN)
