Poor Khianna.  Let's help her out.

For the original recipe she needs [tex]1 \frac 1 2 = \frac 3 2[/tex] cups of brown sugar but only has [tex]1 \frac 1 8 = \frac 9 8 .[/tex]  So the fraction of the brown sugar she has is

[tex]\dfrac{ \frac{9}{8} }{\frac 3 2} = \frac 9 8 \times \frac 2 3 = \frac 3 4[/tex]

She has to scale everything by a factor of  [tex]\frac 3 4[/tex]

I won't multiply everything by 3/4 for you.  2 cups butter becomes 1 and a half cups butter, 1 tsp vanilla becomes 3/4 tsp, etc.
