Question

in 2004, 11.65 million people between the ages of 18 and 24 voted ( compared to 47.3 million voters between the ages of 45 and 64). if the united states has a population of 24.9 million people between the ages of 18 and 24, what percentage of those people voted?

Answer 1

Namely, what is 11.65 in percentage from 24.9

if we take 24.9 to be the 100%, let's see

$\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 24.9&100\\ 11.65&x \end{array}\implies \cfrac{24.9}{11.65}=\cfrac{100}{x}$

solve for "x".
