Greetings!
We can solve this problem by creating a simple equation:
Let x represent the percent
[tex]21=(\frac{x}{100})(25)[/tex]
Simplify.
[tex]21=(\frac{x}{100})(\frac{25}{1})[/tex]
[tex]21=\frac{25x}{100}[/tex]
Multiply both sides by 100.
[tex](100)(21)=100(\frac{25x}{100})[/tex]
[tex]2100=25x[/tex]
Divide both sides by 25.
[tex]\frac{2100}{25}=\frac{25x}{25}[/tex]
[tex]84=x[/tex]
The Answer Is:
[tex] \left[\begin{array}{ccc}x=84\end{array}\right] [/tex]
21 is 84% of 25.
Hope this helps.
