Final answer:
The ratio in simplest form that compares the number of passengers to the number of cars, given 16 cars and 64 passengers, is 4:1, indicating 4 passengers per car.
Step-by-step explanation:
The question asks to write a ratio that compares the number of passengers to the number of cars if there are 16 cars and 64 passengers scheduled to go to a concert. To find this ratio, we divide the number of passengers by the number of cars:
Ratio = Number of Passengers / Number of Cars = 64 / 16 = 4 / 1
The ratio in simplest form that compares the number of passengers to the number of cars is 4:1. This means that for every car, there are 4 passengers scheduled to go to the concert.
