Answer 2

Answer:

54

Step-by-step explanation:

To find the 3rd proportional is to find the third number in this:

6 : 18 :: 18 : x

To do that, we must know that:

Product of the two extremes = Product of the mean

So applying that knowledge to find x:

6x = 18 x 18

6x = 324

x = 324 ÷ 6

x = 54

Answer: The third proportional is 54
