We have to the ratio between the dried fruit and the sunflower seeds.
We know that the recipe requires 1/2 cup of dried fruit, and 1/8 of sunflower seeds. The ratio would be
[tex]\frac{\frac{1}{2}\text{fruit}}{\frac{1}{8}seeds}=\frac{1\cdot8}{1\cdot2}=4[/tex]
So, the ratio of dried fruit to sunflower seeds in the granola recipe is 4, which means there must be 4 cups of dried fruits per each cup of sunflower seeds.
If we triple the recipe, the ratio won't change, because ratios are constant, that way no matter if you do ten times more of the recipe, the result will be the same, because the ratios is the same too.
