$- \frac{1}{2} \times \frac{3}{5} + \frac{ 3}{2} - \frac{ - 3}{5} \times \frac{5}{4}$

$\frac{3}{5} \: ( \: \frac{ - 1}{2} - \frac{5}{4} \: ) \: + \frac{3}{2}$

$\frac{3}{5} ( \frac{ - 2 - 5}{4} ) \: + \frac{3}{2}$

$\frac{3}{5} ( \frac{ - 7}{4} ) + \frac{3}{2}$

$\frac{ - 20}{20} + \frac{3}{2}$

$\frac{ - 20 + 30}{ 20}$

$\frac{9}{20}$
