To determine how big of a slice each person gets when Ginger shares \( \frac{3}{4} \) of a pizza with 8 people, you can divide \( \frac{3}{4} \) by 8.
\[ \text{Slice size} = \frac{3/4}{8} \]
To divide a fraction by a whole number, you can multiply the denominator of the fraction by the whole number:
\[ \text{Slice size} = \frac{3}{4 \times 8} = \frac{3}{32} \]
Therefore, each person gets \( \frac{3}{32} \) of the pizza.
