9. 5/6 divided by 1/3=2 1/2
11. 1/2 divided by 3/5= 5/6
13. 7/12 divided by 5/6=7/10
15. 3/8 divided by 9= 3 3/8
17. 2/5 divided by 4/7=7/10
19. 6/7 divided by 3/11= 3 1/7
21. 5/6 divided by 5/12=2
23. 7/9 divided by 1/7= 5 4/9
25. 3/5 divided by 9/11=11/15

# 15 is incorrect:
3/8 ÷ 9
= 3/8 ÷ 9/1
= 3/8 x 1/9 = 3/72 = 1/24
The rest are correct 
How come the 9 has to ve over the 1 and the 1 isnt over the 9? I thought I had to add the reciprocal so it'd would be 1/9. I'm confused. =/

Why would you ADD the reciprocal if you multiplied in all the other cases to get the correct answers ??
9 is the same as 9/1
the reciprocal of 9/1 is 1/9
so it becomes 3/8 x 1/9 = 3/72 = 1/24
