    \begin{aligned}<br />
4\frac{4}{5} + 3\frac{7}{8} - 1\frac{5}{6} &= 4\frac{96}{120} + 3\frac{105}{120} - 1\frac{100}{120} \\<br />
&= 6\frac{101}{120}<br />
\end{aligned}


    \begin{aligned}<br />
\frac{4}{9} \times 1\frac{1}{2} \div 3\frac{1}{5} &= \frac{4}{9} \times \frac{3}{2} \div \frac{16}{5} \\<br />
&= \frac{4}{9} \times \frac{3}{2} \times \frac{5}{16} \\<br />
&= \frac{60}{288} \\<br />
&= \frac{5}{24}<br />
\end{aligned}
