<p>Anyone know how to do this? Any help is appreciated:</p>

<p>(12) [ 1/2x times 2x/3 times 3/4x times 4x/5 times ... times 26x/27]</p>

<p>seems to be a geometric equation where times is just multiplication (didnt want to confuse anyone with more x's)</p>

<p>answers are either</p>

<p>a) 4/9

b) 4x/9

c) 4/9x

d) 104x/27

e) 104x/135</p>
