Answer: 3.6 = x
Explanation: To solve for x in the given proportion, we simply use the means-extremes property which states the the product of the extremes, (6)(3), equals the product of the means, (5)(x).
So we have (6)(3) or 18 equals (5)(x) or 5x.
So we have the equation 18 = 5x.
Now dividing both sides by 5, 3.6 = x.
