Answer 1

Step-by-step explanation:

Hello dear

( \frac{2}{11} \times \frac{22}{15} ) + ( \frac{ - 1}{6} \times \frac{3}{4} ) + ( \frac{ - 1}{21} \times \frac{ - 3}{5} ) \\ \\ = \frac{4}{15} + \frac{ - 1}{8} + \frac{ - 1}{35} \\ \\ = \frac{224 - 105 + 24}{840} \\ \\ = \frac{143}{840}

Hope it helps.
