Question 104857
You are right on!
Think of the "per" as "divided by", so:
Population "per" square mile is population "divided by" square miles.
For Asia, you get:
4,028,000,000/17,400 = 231,494 people per square mile.( Rounded to nearest integer, since you normally don't have fractions of people)
For North America:
305,000,000/9,400 = 32,447 people per square mile.
I'll leave the comparison to you!
