Step-by-step explanation:

Answer 2

Answer:

$\frac{ - 2}{9} + ( \frac{ - 3}{7} + \frac{ - 9}{14}) = ( \frac{ - 2}{9} + \frac{ - 3}{7} ) \\ \\ \frac{ - 2}{9} + ( \frac{ - 3 \times 2 - 9}{14} ) = ( \frac{ - 2 \times 7 -3 \times 9}{63} ) \\ \\ \frac{ - 2}{9} + ( \frac{ - 6 - 9}{14} ) = ( \frac{ - 14 - 27}{63} ) \\ \\ \frac{ - 2}{9} - \frac{15}{14} = \frac{ - 41}{63} \\ \\ \frac{ - 15}{14} = \frac{ - 41}{63} + \frac{2}{9} \\ \\ \frac{ - 15}{14} = \frac{ - 41 + 2 \times 7}{63} \\ \\ \frac{ - 15}{14} = \frac{ - 41 + 14}{63} \\ \\ \frac{ - 15}{14} = \frac{ - 27}{63} \\ \\ \frac{ - 15}{14} = \frac{ - 3}{7} \\ \\ \frac{ - 15}{14} + \frac{3}{7} \\ \\ \frac{ - 15 + 3 \times 2}{14} \\ \\ \frac{ - 15 + 6}{14} \\ \\ \frac{ - 9}{14}$

or their is one more way to do this

-2/9+(-3/7+-9/14)=(-2/9+-3/7)

-2/9 -3/7 -9/14 +2/9 +3/7

-2/9 +2/9 -3/7 +3/7 -9/14

0+0-9/14

-9/14
