Question

Facebook is now used by one in every 13 people on earth what is the percent

Answer 1

1/13= x/100 You do what my teachers call "the fish"
1*100=100
100/13=7.6923076930769%
But you could probably round it to 8%

Answer 2

percentage value ≈ 8 %

Explanation:

percentage value = number of people using the social media/Total sample size × 100

The number using the social media is given as 1

The total sample size used is 13

number using the social media = 1

Total sample size = 13

percentage value = number of people using the social media/Total sample size × 100

percentage value = 1/13 × 100

percentage value = 100/13

percentage value = 7.692307692

percentage value ≈ 8 %
