Start by taking the information we know, and write equations to represent the realationships:

1) "1/8 lbs less flour to make bread than to make cookies"
$b=c-\frac{1}{8}$

2) "1/4 lb more flour to make cookies than to make brownies:
$c=w+\frac{1}{4}$

3) "she used 1/2 lb of flour ro make bread"
$b = \frac{1}{2}$

From here you can solve for $w$ using back substitution.
