Answer:

[tex]-\frac{7}{12}[/tex]

Step-by-step explanation:

  1. Write it out: [tex]-\frac{1}{3} - \frac{1}{4}[/tex]  
  2. Find a common denominator: 12
  3. Alter the numerators, so they fit the denominators: 1 × 4 = 4, 1 × 3 = 3
  4. Put the new numerators over the denominators: -4/12 - 3/12
  5. [tex]-\frac{4}{12} - \frac{3}{12} = -\frac{7}{12}[/tex]  

I hope this helps!
