To find out how many cookies each person gets, we first need to determine the total number of people sharing the cookies. Tia has 4 friends, so there are a total of 5 people (Tia + 4 friends).
Next, we divide the total number of cookies by the total number of people:
\[ \text{Cookies per person} = \frac{8 \text{ cookies}}{5 \text{ people}} = \frac{8}{5} \]
So, the fraction that shows how many cookies each person gets is 8/5.
