Just for clarity that is 1 over 2 (as in a half, I don't know how to make it look like it does on my page using my computer keyboard).

The answer they gave is:

2A - ah

--------

h

I got...

2A - a

--------

h

I'm confused about how the h ended up on the top and the bottom of the equation when you would be simply multiplying by 1 over h or should you be working out the expression so that is becomes ah + bh first?
