The population of africa is 6.582•10^14 people. the population of australia is 4.32•10^14. how many times the population of australia is africa?

So austraia times x=africa=(4.32*10^14)x=6.582*10^14
to find x, we divde both sides by (4.32*10^14) so
x=(6.582*10^14)/(4.32*10^14)
we know that the exponents will cancel out {([10^14]/[10^14])=1} so
x=6.582/4.32
if you do this on a calculator you get
6.582/4.32=1.5=x
so autralia times 1.5=africa
