Question

What is the solution for x in the proportion 12 / 22 = x / 99.? Describe your steps.

My Answer:

12/22 = x/99
(multiplying by 99)

(12 * 99)/22 = x

x = (12 * 9)/2 (dividing numerator and denominator by 11 in right hand side

x = 6 * 9

x = 54

Is this right? did I do anything wrong or am I good to go?
