<p>WAS THIS ONE IN AN EXPERIMENTAL SECTION I THINK I MISSED IT!</p>

<p>if a=1/b,</p>

<p>so what is the value of 1-a/1-b</p>

2

<p>Sub in 1/b for a in the expression (1-a)/(1-b)</p>

<p>(1-1/b)/(1-b) now multiply whole term by b/b</p>

<p>(b-1)/b(1-b) you can see that since b-1 = -(1-b) then (b-1)/(1-b) = -1</p>

<p>-1/b this is your answer</p>
