From the first graph you can see that Perth accounts for 6% of Australia's population. The second graph tells you that all of Western Australia accounts for 9% of Australia's population. So the population of Western Australia outside of Perth accounts for 9% – 6% = 3% of Australia's population. The first graph tells you that 42% of Australia's population lives in cities with less than 1 million people or rural areas. So the percent of Australians who live in cities with less than 1 million people or rural areas that live in Western Australia is
\(\frac{3}{42}* 100= \frac{1}{14} = about 7%\)
B is the answer
\(\frac{3}{42}* 100= \frac{1}{14} = about 7%\)
B is the answer
