To determine how many servings of pasta are in the 8 boxes, we first need to understand how many servings are in one box. Since each serving is \( \frac{1}{6} \) of a box, the number of servings in one box can be calculated as follows:
\[ \text{Number of servings in one box} = \frac{1}{\frac{1}{6}} = 6 \]
This means each box contains 6 servings of pasta.
Now, if there are 8 boxes, we can calculate the total number of servings by multiplying the number of servings in one box by the total number of boxes:
\[ \text{Total servings} = \text{Number of boxes} \times \text{Servings per box} = 8 \times 6 = 48 \]
Thus, there are \( \boxed{48} \) servings of pasta in the 8 boxes on the shelf.
