I recently thought of this brain teaser and was thinking that people where would enjoy.

1/2 - 1/4 = 3
1/30 - 2/5 = 7
3/4 - 3/10 = ?Enjoy :smile:

I can think of one pattern, which would give 7/9 as the answer, but 2 examples aren't enough for me to say. I'll try finding something else. And oh, who's Brian?

Brian is a horrible speller!

how about another example:

4/5 - 5/6 = 32
 
:confused:
 
Sorry Diffy, I haven't had much time to look at it. I'll try to solve it by the end of the day.
