  need to solve 6-6i/-9i
  
  came up with the answer 2/3 + 2/3i
  
  What am I doing wrong. It's showing up as incorrect.
  
  Thank you.

  You're missing a negative sign
  
  $\frac{6-6i}{-9i}=\frac{2-2i}{-3i}=\frac{2-2i}{-3i}\cdot \frac{i}{i}=\frac{2i-2i^2}{-3i^2}=\frac{2i+2}{3}$

  Hello, needhelpnow!
  
  Simplify: $\frac{6-6i}{-9i}$
  
  Came up with the answer 2/3 + 2/3i
  
  What am I doing wrong? It's showing up as incorrect.
  
  Your answer, $\tfrac{2}{3} + \tfrac{2}{3}i$, is correct.
  
  . . it might be read as: $\tfrac{2}{3} + \tfrac{2}{3i}$
  
  Try entering it as. 2/3 + 2i/3. or .2/3 + (2/3)i.
