let
x-----------> the number

we know that
\(25\) % is equal to  \(\frac{25}{100}\)
\((\frac{25}{100})*x=9\)
multiply by 100 both sides 
\(25*x=900\)
divide  by 25 both sides
\(x= \frac{900}{25} \\ x=36\)

the answer is
the number is \(36\)

Answer: 36

Step-by-step explanation:

Let the number be x

Thus we can write:

\(25\%\times x=9\)

\(\frac{25}{100}\times x=9\)

\(x=\frac{9\times 100}{25}\)

\(x=36\)

Thus 25% of 36 is 9.
