Question

about 3/5 of the world's population lives in Asia and the people of Europe's makes about 3/25 of the world's population what fraction of the population world's population live in either Asia or Europe​

Answer 1

Answer:

Asia = 3/5

Europe = 3/25

LCM=25

3/5 x 5/5 = 15/25

Fraction in both = 15/25 + 3/25

                          = 18/25 of total population

Answer 2

Answer :

• 18/25

Given :

• Population of world in Asia = 3/5
• Population of world in Europe = 3/25

To find :

• Population together in Asia and Europe

Solution :

Let the total population of earth be x .

A/Q ,

Population of Asia = 3/5 of world's population

$= \tt \dfrac{3}{5} \times x$

$\tt \: = \dfrac{3x}{5}$

Population of Europe = 3/25 of world's population

$= \tt \dfrac{3}{25} \times x$

$\tt = \dfrac{3x}{25}$

Total population either living in Europe or asia

= Population in Asia + Population in Europe

$= \tt \: \dfrac{3x}{5} + \dfrac{3x}{25} \\ \\ = \tt \frac{15x + 3x}{25} \\ \\ = \tt \frac{18x}{25} \\ \\ = \tt \: \frac{18}{25} \times x$

Hence , the fraction of world population living in either Asia or Europe is 18/25 .
