To find out how much pizza each friend gets, you need to divide the amount of pizza shared (7/8) by the number of friends (4).
The calculation is as follows:
\[ \frac{7/8}{4} = \frac{7}{8} \times \frac{1}{4} = \frac{7 \times 1}{8 \times 4} = \frac{7}{32} \]
So, each person gets \( \frac{7}{32} \) of a pizza.
