Final answer:
The ratio of profit to revenue is 5/186.
Step-by-step explanation:
To compare the profit to revenue, we can express the ratio of profit to revenue as a fraction. The profit is given as approximately $500 million, and the revenue is given as approximately $18,600 million. To write this as a fraction in lowest terms, we divide both the profit and revenue by their greatest common divisor, which is 1000.
This gives us a ratio of 500/18600. Simplifying this fraction further, we can divide both the numerator and denominator by 100 to get the final ratio of 5/186.
The correct answer is 5/186.
