Greetings!
We can solve this problem by creating a simple equation:
Let x represent the percent.
[tex]19=( \frac{x}{100})(76)[/tex]
Simplify.
[tex]19=(\frac{x}{100})(\frac{76}{1})[/tex]
[tex]19=(\frac{76x}{100})[/tex]
Multiply both sides by 100.
[tex](19)(100)=(100)[(\frac{76x}{100})][/tex]
[tex]1900=76x[/tex]
Divide both sides by 76.
[tex] \frac{1900}{76}= \frac{76x}{76}[/tex]
[tex]25=x[/tex]
The Answer Is:
[tex] \left[\begin{array}{ccc}x=25\end{array}\right] [/tex]
Hope this helps.
