Answer 1

$\frac{ - 2}{5} + ( \frac{3}{10} \div \frac{1}{2} ) - \frac{1}{2} \\ \\ \\ = \frac{ - 2}{5} + ( \frac{3}{10} \times 2 ) - \frac{1}{2} \\ \\ \\ = \frac{ - 2}{5} + \frac{3}{5} - \frac{1}{2} \\ \\ \\ = \frac{ - 2 + 3}{5} - \frac{1}{2} \\ \\ \\ = \frac{1}{5} - \frac{1}{2} \\ \\ \\ = \frac{2 - 5}{10} \: \: \: \: \: \: \: (lcm = 10) \\ \\ \\ = \frac{ - 3}{5}$
