Question

Internet live stats.com reported in December 2017 around 40% of the world population has an internet connection today. If there are 3,064,486,185 users, what is the world population? Round to the nearest whole number

Answer 1

Since 40% of population is 3,064,486,185

Then to find 100% we will use the cross multiplication

`\begin{gathered} (40)/(3064486185)=(100)/(x) \\ 40* x=100*3064486185 \end{gathered}`

Divide both sides by 40 to find x

`\begin{gathered} (40x)/(40)=(306448618500)/(40) \\ x=7661215463 \end{gathered}`

The world population is 7,661,215,463
