Step-by-step explanation:
Given as :
The estimated population of world in 2050 = 9,000,000,000
The population of Africa is 20% of world population
Let The estimated population of Africa in 2050 = x
So, According to question
The estimated population of Africa in 2050 = 20 % of estimated population of world in 2050
Or, x = 20 % × 9,000,000,000
Or, x = [tex]\dfrac{20}{100}[/tex] × 9,000,000,000
Or, x = [tex]\dfrac{20\times 9,000,000,000}{100}[/tex]
∴ x = 1,800,000,000
The estimated population of Africa in 2050 = x = 1,800,000,000
Hence, The estimated population of Africa in 2050 is 1 billion 8 hundred million . Answer
