Mention way through which the percentage of Africa can be calculated?

The percentage of Africa can be calculated by dividing the land area of Africa by the total land area of the Earth and then multiplying by 100. Alternatively, the percentage of Africa can also be calculated by dividing the population of Africa by the total population of the Earth and then multiplying by 100.

Ways to Calculate Africa's Percentage:

1. Area:
- Total area of Earth: 510.1 million km²
- Area of Africa: 30.37 million km²
- Percentage of Africa = (Area of Africa / Total area of Earth) x 100
- Percentage = (30.37 / 510.1) x 100 = 5.95%

2. Population:
- Total world population: 8 billion
- Population of Africa: 1.417 billion
- Percentage of Africa = (Population of Africa / Total world population) x 100
- Percentage = (1.417 / 8) x 100 = 17.7%

3. GDP (Gross Domestic Product):
- Total world GDP: $86.97 trillion
- GDP of Africa: $2.94 trillion
- Percentage of Africa = (GDP of Africa / Total world GDP) x 100
- Percentage = (2.94 / 86.97) x 100 = 3.39%

4. Number of Countries:
- Total number of countries in the world: 195
- Number of countries in Africa: 54
- Percentage of Africa = (Number of countries in Africa / Total number of countries) x 100
- Percentage = (54 / 195) x 100 = 27.7%
