Question

In 2018, the population of China was 1.386 billion people,If the Wuhan population in China in 2018 was 11.08 million people, calculate the percent of people in China who were in Wuhan in 2018

Answer 1

We have that 1 billion people = 1.000'000.000

Then we first calulate how much is 0.386 billion:

So we have:

386000000

So the total were:

1386000000, now:

If 1386000000 represents 100% of the population, then what percentage of the population does 11080000 represent:

then we have:

$T=\frac{11080000\cdot100}{1386000000}\Rightarrow T=\frac{559}{693}\Rightarrow T=0.7994227994\Rightarrow T\approx0.8$

Wuhan had aprox the 0.8% of the total population of china on 2018.
