To determine how many pizzas Hannah needs for 28 guests, we can set up a proportion based on the ratio of pizzas to guests.
Hannah needs 2 pizzas for every 7 guests. We can start by finding out how many groups of 7 guests are in 28 guests:
\[
\text{Number of groups} = \frac{28}{7} = 4
\]
Since she needs 2 pizzas for each group of 7 guests, we can now calculate the total number of pizzas needed:
\[
\text{Total pizzas} = 4 \text{ groups} \times 2 \text{ pizzas/group} = 8 \text{ pizzas}
\]
Thus, Hannah needs **8 pizzas** for 28 guests.
