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

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

the answer is
the number is [tex]36[/tex]

Answer: 36

Step-by-step explanation:

Let the number be x

Thus we can write:

[tex]25\%\times x=9[/tex]

[tex]\frac{25}{100}\times x=9[/tex]

[tex]x=\frac{9\times 100}{25}[/tex]

[tex]x=36[/tex]

Thus 25% of 36 is 9.
