Answer 1

Answer:

Approximately 18.7% people lived without clean drinking​ water.

Step-by-step explanation:

Given:

Total Number of people living in the world = $5.35\times10^9$

Number of people didn't have access to clean drinking water = $1\times10^9$

We need to find the approximately what percent of them lived without clean drinking​ water.

Solution:

Now we can say that;

To find the percent of people lived without clean drinking​ water can be calculated by Number of people didn't have access to clean drinking water divided by Total Number of people living in the world multiplied by 100.

framing in equation form we get;

percent of people lived without clean drinking​ water = $\frac{1\times10^9}{5.35\times 10^9}\times 100 \approx 18.7\%$

Hence Approximately 18.7% people lived without clean drinking​ water.
