Answer:
[tex]-\frac{21}{10}[/tex] or [tex]-2.1[/tex] (they're the same)
Step-by-step explanation:
- Simplify: [tex]-\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}[/tex]
- 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
- Write the new fractions: [tex]-\frac{45}{30} - \frac{18}{30}[/tex]
- Subtract: -45/30 - 18/30 = [tex]-\frac{63}{30} = -\frac{21}{10}[/tex]
I hope this helps!
