To find out how much flour is in each biscuit, we need to divide the total amount of flour by the number of biscuits.
Alec uses 8 cups of flour to make 25 biscuits. We can calculate the amount of flour per biscuit as follows:
\[ \text{Flour per biscuit} = \frac{\text{Total flour}}{\text{Number of biscuits}} = \frac{8 \text{ cups}}{25 \text{ biscuits}} \]
So, the amount of flour in each biscuit is:
\[ \frac{8}{25} \text{ cups} \]
Thus, there is \(\frac{8}{25}\) cups of flour in each biscuit.
