\(\frac{3}{10}\left(-\frac{5}{3}+\frac{3}{5}\right)+\left(-\frac{3}{10}\right)\left(\frac{3}{9}+\left(-\frac{2}{5}\right)\right)=\frac{3}{10}\left(-\frac{5}{3}+\frac{3}{5}-\frac{3}{9}+\frac{2}{5}\right)\)
\(=\frac{3}{10}\left(-\frac{18}{9}+\frac{5}{5}\right)\)
\(=\frac{3}{10}\left(-2+1\right)\)
\(=\frac{3}{10}.\left(-1\right)\)
\(=-\frac{3}{10}\)
