 Question from Bethmarie: What percentage of the world population (7.5 billion) is Canada's population (36 million). Thank you very much!

Hi Bethmarie,

$7.5$ billion is $7.5 \times 10^9 = 7,500,000,000$ and $36$ million is $36 \times 10^6 = 36,000,000.$ Hence the fraction of the world population that is canadian is

$\frac{36,000,000}{7,500,000,000}.$

To convert that to a percentage multiply by 100.
