Step 1 :Let's assume the percentage of people who answered 'Yes' is given as 60%.
Step 2 :We need to calculate 60% of 630 people to find out how many people answered 'Yes'.
Step 3 :\(\text{Yes Count} = \frac{\text{Total People} \times \text{Yes Percentage}}{100}\)
Step 4 :\(\text{Yes Count} = \frac{630 \times 60}{100}\)
Step 5 :\(\text{Yes Count} = 378\)
Step 6 :\(\boxed{378}\) people answered with 'Yes'.
