Answer:
The way they put it, you would need to use ratios to compare the landmass of a region of Canada to another region of Canada. I don't know if this helps but I hope it does!
EDIT:
1/6 of the land is 7,451,000 people
1/9 of the land is 12,178,000 people
Total population is 30,647,000 people
Google helped sort of:
The West takes up 29/100 of Canada
The Territories takes up 39/100 of Canada
The Atlantic takes up something (Google wouldn't tell me)
39/100 of 30,647,000 is 11,952,330 people but there's only 99,000 people living there?
