Пошаговое объяснение:

1) -56 + 44 = -12

2) -384,56 + (-126,34) = -384,56 - 126,34 = -510,9

3) -13,356 + (-8,93) = -13,356 - 8,93 = -22,286

4) $-\frac{4}{9} + (-\frac{3}{5} ) = - \frac{4}{9} - \frac{3}{5} = \frac{-20 - 27}{45} = \frac{-47}{45} = 1\frac{2}{45}$

5) $-\frac{11}{25} + (- \frac{13}{5} ) = -\frac{11}{25} - \frac{13}{5} = \frac{-11 - 65}{25} = \frac{-76}{25} = -3\frac{1}{25}$

6) $-\frac{7}{24} + (-\frac{5}{12} ) = -\frac{7}{24} -\frac{5}{12} = \frac{-7 - 10}{24} = -\frac{17}{24}$

7) $-\frac{9}{14} + (-\frac{13}{21} ) = -\frac{9}{14} -\frac{13}{21} =\frac{-63 - 13}{21} = -\frac{76}{21} = -3\frac{13}{21}$

8) $-\frac{11}{20} + (-\frac{9}{16} ) = -\frac{11}{20} -\frac{9}{16} = \frac{-44 - 45 }{80} = -\frac{89}{80} = -1\frac{9}{80}$
