Give
the solution proportion of the given number
=> x : 45 = 8 : 18
=> Let’s start solving the proportion
=> 45 8 = 360
=> 360 / 18 =20
Thus the answer is letter B. X = 20
let’s check if we have correct answer
=> 20 18 = 360
=> 360 / 45 = 8
=> 20 * 18 = 360
=> 360 / 8 = 45
Thus, we have the same answer.
