Solution for the given fractions

$ -\frac{5}{4 }-\frac{ 6}{(-5)} =? $

The common denominator of the two fractions is: 20

$ -\frac{5}{4 }= \frac{(-5*5)}{(4*5)} = -\frac{25}{20} $

$ \frac{6}{(-5)} = \frac{(-4*6)}{(-5*(-4))} = -\frac{24}{20} $

Fractions adjusted to a common denominator

$ -\frac{5}{4 }-\frac{ 6}{(-5)} = -\frac{25}{20 }- -\frac{24}{20} $

$ -\frac{25}{20 }- -\frac{24}{20 }= \frac{(24-25)}{20} $

$ \frac{(24-25)}{20 }= -\frac{1}{20} $
