    Since this is a proportion, we cross multiply.

    12/2=9/x (The variable "x" is used the represent the unknown number, and this is the number we are solving for)

    12*x=2*9 (Cross multiply)

    12x=18 (Simplify)

    x=18/12 (Divide each side by 12)

    x = 3/2 (Simplify fraction)

    The unknown number is 3/2, or 1.5.

    Well 12/2 equals 6 When Simplified. So that means 6=9/x.

    9 divided by 6 is 1.5 which makes x=1.5.

    12/2=9/1.5
