$\LARGE{} \dfrac{4.5}{16.2} \\ \\ \LARGE{} \frac{ \dfrac{9}{2} }{ \frac{81}{5} } \\ \\ \LARGE{} \dfrac{9}{2} \div \dfrac{81}{5} \\ \\ \LARGE{} \dfrac{9}{2} \times \dfrac{5}{81} \\ \\ \LARGE{} \dfrac{9 \times 5}{2 \times 81} \\ \\ \LARGE{} \dfrac{\cancel{9} \times 5}{2 \times \cancel{81}} \\ \\ \LARGE{} \frac{5}{2 \times 9} \\ \\ \LARGE\boxed{ \frac{5}{18} }$
