Answer 2

Answer

$\huge - \frac{2}{3} \times \frac{3}{5} + \frac{5}{2} - \frac{3}{5} \times \frac{1}{6}$

$\huge \: - \frac{2}{3} \times \frac{3}{5} - \frac{3}{5} \times \frac{1}{6} + \frac{5}{2}$

$\huge \: \frac{3}{5} ( \frac{ - 2}{3} - \frac{1}{6}) + \frac{5}{2}$

$\huge \: ( \frac{ - 2 \times 2 - 1}{6} + \frac{5}{2} \: )$

$\huge \: \frac{3}{5}( \frac{ - 4 - 1}{6} ) + \frac{5}{2}$
