\bf \cfrac{4\frac{1}{2}}{\quad \frac{2}{3}\quad }\implies \cfrac{\frac{4\cdot 2+1}{2}}{\quad \frac{2}{3}\quad }\implies \cfrac{\frac{9}{2}}{\quad \frac{2}{3}\quad }\implies \cfrac{9}{2}\cdot \cfrac{3}{2}\implies \cfrac{27}{4}\implies 6\frac{3}{4}
\\\\\\
\textit{so, 6 whole pieces, and }\frac{3}{4}\textit{ of another one}

now, what's the leftover?  well, 3/4 of the last one, namely 3/4 of 2/3, what is 3/4 of 2/3 anyway?  well, is just their product,

\bf \cfrac{\underline{3}}{4}\cdot \cfrac{2}{\underline{3}}\implies \cfrac{2}{4}\implies \stackrel{lbs}{\cfrac{1}{2}}
