# $(\begin{array}{l} \left( {\frac{1}{{15}} + 1 - \frac{9}{{10}}} \right) \div \left( {\frac{4}{5}\;of\;\frac{3}{2}} \right)\\ = \left( {\frac{1}{{15}} + 1 - \frac{9}{{10}}} \right) \div \left( {\frac{4}{5} \times \frac{3}{2}} \right)\\ = \left( {\frac{1}{{15}} + 1 - \frac{9}{{10}}} \right) \div \frac{6}{5}\\ = \frac{{2 + 30 - 9 \times 3}}{{30}} \div \frac{6}{5}\\ = \frac{5}{{30}} \div \frac{6}{5}\\ = \frac{5}{{30}} \times \frac{5}{6} \end{array})$
= 5/36
