plz solve this question​

Answer 1

Answer:

$= - 20 + ( \frac{ - 3}{5} + \frac{7}{10} ) = ( - 20 - \frac{3}{5} ) + \frac{7}{10} \\ \\ = - 20 + \frac{ - 6 + 7}{10} = - \frac{103}{5} + \frac{7}{10} \\ \\ = - 20 + \frac{1}{10} = \frac{ - 206 + 7}{10} \\ \\ = \frac{ - 200 + 1}{10} = \frac{ - 201}{10} \\ \\ = - \frac{ - 199}{10} = \frac{ - 201}{10}$
