Total number of the adults are 693

Percentage of adults that show that they erase all of their personal information online is 58%

Geberal expression for the percentage is


Percentage=\frac{\text{value to whose percentage to be found}}{\text{Total value}}*100

We need to find the number of adults that erase all of their personal information online.


Percantage=\frac{Number\text{ of the adults who erase thier personal informatio}}{\text{Total number of adults}}*100

Substitute the value

Let x=Number of adults who erase thier personal information


58=(x)/(693)*100

Simplify and solve for, x


\begin{gathered} 58*693=100x \\ (40194)/(100)=x \\ x=401.94 \end{gathered}

Round of the x value


x=402

Number of adults who erase thier personal information are 402.
