What is 3.9 billion divide by 317 million?

Answer 1

0.0123

Answer 2

* in those countries that use the long scale (based on powers of a million) like Europe:

3.9 billion ÷ 317 million = (3.9 x (10^6)^2) ÷ (317 x 10^6) ≈ 0.0123 x 10^6 = 12,300

* in those countries that use the short scale (based on powers of a thousand plus one) like USA:

3.9 billion ÷ 317 million = (3.9 x (10^3)^(2+1)) ÷ (317 x 10^6) ≈ 0.0123 x 10^3 = 12.3
