Solution for the given fractions

$ -\frac{6}{7 }+\frac{ 3}{(-14)} =? $

The common denominator of the two fractions is: 14

$ -\frac{6}{7 }= \frac{(-6*2)}{(2*7)} = -\frac{12}{14} $

$ \frac{3}{(-14)} = \frac{(-1*3)}{(-14*(-1))} = -\frac{3}{14} $

Fractions adjusted to a common denominator

$ -\frac{6}{7 }+\frac{ 3}{(-14)} = -\frac{12}{14 }+ -\frac{3}{14} $

$ -\frac{12}{14 }+ -\frac{3}{14 }= \frac{(-12-3)}{14} $

$ \frac{(-12-3)}{14 }= -\frac{15}{14} $
