-6 / 5 x (-25 / 3) 
Multiply straight across; the negative cancels out. 
150 / 15
This can be reduced to 15, which is its simplest form.
        
                    
             
        
        
        
Answer:
4/15
Step-by-step explanation:

5/15 + 6/15
11/15
Subtract this from 1 for the entire circle
15/15 -11/15
4/15
4/15 is shaded
