1. The problem asks for the fraction of people whose favourite pizza topping was pepperoni based on the pie chart. 2. A full pie chart represents a total of 360 degrees, which corresponds to all people surveyed. 3. The pepperoni section measures 45 degrees. 4. To find the fraction of people who chose pepperoni, divide the pepperoni angle by the total angle: $$\frac{45}{360}$$ 5. Simplify the fraction by dividing numerator and denominator by 45: $$\frac{45 \div 45}{360 \div 45} = \frac{1}{8}$$ 6. Therefore, the fraction of people who said their favourite pizza topping was pepperoni is $\frac{1}{8}$.
