Divide. Write in simplest form.
5. 1/3 divided by 2/5=5/6
6. 1/9 divided by 1/2=2/9
7.2/3 divided by 1/4=8/3=2 2/3
8. 1/2 divided by 3/4=4/6=2/3
9. 4/5 divided by 2=1 3/5
10. 4/5 divided by 1/10=40/5=8
11. 5/12 divided by 5/6=30/60=1/2
12. 9/10 divided by 3= 2 7/10

9 and 12 are wrong. It looks as though you forgot to multiply by the reciprocal.
The others are right. 
For number nine 2 would become 1/2 and for number 12 3 would be 1/3?

Yes.

I did cross multiplication to get my answer 4x2=8 and 5x1=5 and I got 8/5 for number 9. Is that right? And then I divided to get my answer.

IS number 9 4/10 which equals 2/5

12 is 3/10

Yes. Now they are both right.

Thank you

You're welcome.
