Step-by-step explanation:

$\large (\frac{ - 9}{10}) + \frac{22}{15} + ( \frac{ - 13}{ 20}) \\ \\ \large \: taking \: \: lcm \\ \\\large (\frac{ - 9 \times 6}{10 \times 6} ) + \frac{22 \times 4}{15 \times 4} + ( \frac{ - 13 \times 3}{ 20 \times 3} ) \\ \\ \large( \frac{ - 54}{60}) + \frac{88}{60} + (\frac{ - 39}{60}) \\ \\ \large \frac{ - 54 + 88 - 39}{60} \\ \\ \large \red{\frac{ - 5}{60} = \frac{ - 1}{12} }$
