Answer 1

Let number is x..
According to qs: 4/9 x= 12
4x= 108
=> x= 27
Number is 27

Answer 2

let the number be 'x'
so according to the question
  4/9 x=12
        x=12X9/4           (WHILE TRANSPOSING FROM RHS TO LHS WE HAVE TO
                                     TAKE THE RECIPROCAL so , 4/9 becomes 9/4)
        x=108/4
        x=27
so the number is 27...
