  ##### (v) (-1/18) and (-7/27)
  
  Solution: (-1/18) and (-7/27)
  
  = (-3 + (-14)/54
  
  = (-3 -14)/54
  
  = (-17/54)
  
  ##### (vi) (21/-4) and (-11/8)
  
  Solution: (21/-4) and (-11/8)
  
  = (-42 + (-11)/8
  
  = (-42 – 11)/8
  
  = (-53/8)
  
  #### 3. Evaluate :
  
  ##### (i) (2/-3) + (-4/9)
  
  Solution: (2/-3) + (-4/9)
