Final answer:
Approximately 93.46% of viewers watch the Macy's Thanksgiving Day Parade on television, while approximately 6.54% watch it live in person.
Step-by-step explanation:
To determine the percentage of viewers who watch the Macy's Thanksgiving Day Parade on television, we divide the number of people who watch it on television by the total number of viewers. In this case, 50 million people watch it on television, so we divide 50 million by the total viewership of 53.5 million (3.5 million in person + 50 million on television). This gives us a percentage of approximately 93.46%.
To determine the percentage of viewers who watch the parade live in person, we divide the number of people who watch it in person by the total number of viewers. In this case, 3.5 million people watch it in person, so we divide 3.5 million by the total viewership of 53.5 million. This gives us a percentage of approximately 6.54%.
