To find out what percentage of the seats are filled, we can use the formula for percentage:
Percentage = (Number of people in the cinema / Total number of seats) × 100
In this case, we have 98 people in the cinema and a total of 280 seats.
So, we can substitute the values into the formula:
Percentage = (98 / 280) × 100
Now, we first divide 98 by 280:
98 / 280 = 0.35
Next, we multiply by 100 to find the percentage:
0.35 × 100 = 35
Therefore, 35% of the seats in the cinema are filled when 98 people are present.
