Answer:
(-8)/27
Explanation:
Simplify the following: 
(-2)/(3 (2 + 1/4)) 
 
Put 2 + 1/4 over the common denominator 4. 2 + 1/4 = (4×2)/4 + 1/4: 
(-2)/(3 (4×2)/4 + 1/4) 
 
4×2 = 8: 
(-2)/(3 (8/4 + 1/4)) 
 
8/4 + 1/4 = (8 + 1)/4: 
(-2)/(3 (8 + 1)/4) 
 
8 + 1 = 9: 
((-2)/3)/(9/4) 
 
Multiply the numerator by the reciprocal of the denominator, ((-2)/3)/(9/4) = (-2)/3×4/9: 
(-2×4)/(3×9) 
 
3×9 = 27: 
(-2×4)/27 
 
-2×4 = -8:
