First off, we'll convert the mixed fraction to "improper" and proceed,

$\bf \stackrel{mixed}{10\frac{4}{5}}\implies \cfrac{10\cdot 5+4}{5}\implies \stackrel{improper}{\cfrac{54}{5}}\\\\
-------------------------------\\\\
\cfrac{icing}{cake}\qquad \cfrac{\quad \frac{54}{5}\quad }{\frac{1}{4}}\implies \cfrac{54}{5}\cdot \cfrac{4}{1}\implies \cfrac{216}{5}\implies \cfrac{43\frac{1}{5}}{1}$
