Sagot :

Given the statements in the image, 2% of the fans implies that 2/100 of the fans in attendance equals to 120 teenagers. i.e,

[tex]\frac{2}{100}\text{ of fans }=120[/tex]

Let the total number of fans equal to x. We have the following ratio:

[tex]\frac{2}{100}=\frac{120}{x}[/tex]

To get x by scaling up our ratios, we multiply both numerator and denominator by a common factor of 60 to have:

It can be seen that:

[tex]\begin{gathered} 2\times60=120 \\ 100\times60=x \\ 6000=x \\ x=6000 \end{gathered}[/tex]

Hence, the total number of people at the stadium is 6000.
