Answer 1

The estimated population of Africa in 2050 is 1 billion 8 hundred million .

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 =
`(20)/(100)` × 9,000,000,000

Or, x =
`(20* 9,000,000,000)/(100)`

∴ 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
