In triangle $\triangle ABC$, $\angle A = 60^{\circ}$ and $\angle B = 45^{\circ}$. A line $DE$, with $D$ on $AB$ and $E$ on $BC$, such that $\angle ADE = 75^{\circ}$, divides $\triangle ABC$ into two parts where the area of $\triangle ADE$ is one third of the area of $\triangle ABC$. Find the ratio $\frac{AD}{AB}$.
