    Answer:

    270 & 30

    Step-by-step explanation:

    let the number is n,

    the equation :

    n× 1/9 n= 27(n +1/9 n)

    1/9 n² = 27n + 3n

    1/9 n² = 30n

    1/9n²- 30n = 0

    n(1/9n -30)= 0

    n = 0 or

    1/9n = 30 => n = 30×9 = 270

    270 is a number,

    the other : 270/9 = 30
