Question

-1+(-2/3+-3/4)=(-1+ -2/3)+ -3/4

Answer 1

Answer:

$- 1 + ( \frac{ - 2}{3} - \frac{3}{4} ) = ( - 1 - \frac{2}{3}) - \frac{3}{4} \\ - 1 + ( \frac{ - 8 - 9}{12} ) = ( \frac{ - 3 - 2}{3} ) - \frac{3}{4} \\ - 1 + ( \frac{ - 17}{12} ) = ( \frac{ - 5}{3} ) - \frac{3}{4} \\ - 1 - \frac{17}{12} = \frac{ - 5}{3} - \frac{3}{4} \\ \frac{ - 12 - 17}{12} = \frac{ - 20 - 9}{12} \\ \frac{ - 29}{12} = \frac{ - 29}{12} \\ \frac{29}{12} = \frac{29}{12}$
