Can you show your work 12/2=9/?

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
