Final answer:

China could expect approximately 2.83 x 10^4 visitors if their visitors were proportional to Chicago.

Step-by-step explanation:

To find out how many visitors China could expect if their visitors were proportional to Chicago, we can set up a proportion based on the ratio of the populations of the two places. The population of Chicago is 2.706 million and it receives 55 million visitors a year. Let's call the number of visitors China could expect 'x'. So, the proportion would be:

2.706 million / 55 million = 1.393 billion / x

Cross multiplying, we get:

2.706 million * x = 55 million * 1.393 billion

Simplifying the right side, we have:

2.706 million * x = 76.615635 billion

Dividing both sides by 2.706 million, we get:

x = 76.615635 billion / 2.706 million

x = 28,331.225

Rounded to two decimal places and written in scientific notation, China could expect approximately 2.83 x 10^4 visitors.
