Answer:

-\frac{21}{10} or -2.1 (they're the same)

Step-by-step explanation:

  1. Simplify: -\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}  
  2. Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18
  3. Write the new fractions: -\frac{45}{30} - \frac{18}{30}  
  4. Subtract: -45/30 - 18/30 = -\frac{63}{30} = -\frac{21}{10}

I hope this helps!
