brown sugar= $\frac{3}{8}$

white sugar= $\frac{1}{3}$

you need to mix brown sugar with white sugar

$\frac{3}{8}$ + $\frac{1}{3}$ = $\frac{9+8}{24}$ = $\frac{17}{24}$

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was $\frac{17}{24}$ , so

$\frac{17}{24}$ - $\frac{1}{4}$ = $\frac{68-24}{96}$ = $\frac{11}{24}$

The sugar mixture used to make the cake is $\frac{11}{24}$
