yes

To find the percentage, you can use the following formula:

(Change in value / Original value) x 100

First, let's calculate the change in the number of Facebook users from 2010 to 2011:

Change in value = 845 million - 608 million = 237 million

Now, we plug these values into the formula:

(237 million / 608 million) x 100 = 0.389 x 100 = 38.9%

So, the percentage increase in Facebook users from 2010 to 2011 is approximately 38.9%.

To check whether Facebook is used by 1 in every 13 people on earth, we can calculate the percentage of the world population that uses Facebook:

Percentage = (Number of Facebook users / World population) x 100

Let's assume the current world population is approximately 7.9 billion (as of April 2021).

Number of Facebook users = 845 million

Percentage = (845 million / 7.9 billion) x 100 = 0.107 x 100 = 10.7%

So, currently, Facebook is used by approximately 10.7% of the world population.

To calculate the percentage of people who use Facebook out of every 13 people on earth, we divide the percentage of Facebook users by 13:

Percentage since Facebook is used by 1 in every 13 people on earth = 10.7% / 13 ≈ 0.823%

Therefore, the percentage since Facebook is used by 1 in every 13 people on earth is approximately 0.823%.
