[MATH]9=\frac{x}{100}\cdot36[/MATH]

"9 is" becomes "9 =" and "what percent" becomes "x/100" and "of 36" becomes "·36".

Multiply through by [MATH]\frac{100}{9}[/MATH]

[MATH]100=4x[/MATH]

Divide through by 4 and arrange as:

[MATH]x=25[/MATH]

[MATH]9=\frac{x}{100}\cdot36[/MATH]

"9 is" becomes "9 =" and "what percent" becomes "x/100" and "of 36" becomes "·36".

Multiply through by [MATH]\frac{100}{9}[/MATH]

[MATH]100=4x[/MATH]

Divide through by 4 and arrange as:

[MATH]x=25[/MATH]

Is my method correct?
