= 6.848billion/(.22*57.9million)
Good eye, 22% does play a key role here.
Out of 57.9 land, ONLY 22% is favorable (farms). Multiply, you get 12.738 million square miles of land.
NOW, try dividing 6.848 billion by 12.738 million. BUT, keep in mind the zeros, because billions are higher than millions.
I got 537.6, but be sure to check your work.

6.848*10^9 people
.22*57.9 *10^6 miles^2
so
[ 6.848/(.22*57.9) ]10^3
=.5376 * 10^3
= 538
.22*57.9 *10^6 miles^2
so
[ 6.848/(.22*57.9) ]10^3
=.5376 * 10^3
= 538
Thank you soooo much, y'all made it clear!! @bobpursley @Tony O. @Damon
