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
$\displaystyle \frac{6-6i}{-9i}=\frac{2-2i}{-3i}=\frac{2-2i}{-3i}\cdot \frac{i}{i}=\frac{2i-2i^2}{-3i^2}=\frac{2i+2}{3}$
EDIT: My bad I read the question wrong. I have edited my answer accordingly.
Hello, needhelpnow!
Simplify: $\displaystyle \frac{6-6i}{-9i}$
Came up with the answer 2/3 + 2/3i

Your answer, $\displaystyle \tfrac{2}{3} + \tfrac{2}{3}i$, is correct.
If you entered your answer as 2/3 + 2/3i,
. . it might be read as: $\displaystyle \tfrac{2}{3} + \tfrac{2}{3i}$
Try entering it as. 2/3 + 2i/3. or .2/3 + (2/3)i.
