If I read your attachment correctly, start with the 1 and the fraction at the bottom first, and write them over a common denominator; like this:







You now need 1 over this answer; that's

This is simply the reciprocal of the fraction: turn it 'upside-down':

Now you do a similar thing for the remaining 1 and this new fraction:



Watch that sign!



And so finally (as chiph588@ said) invert and mulitply:







I hope you followed all that.
