To get the missing proportion, we need to multiply 30 by 12 and then divide the answer by 15.

(30)(12) ÷ 15
360 ÷ 15
24

30:12 = 15: 24

The proportion on the left side or shall we say the numerator ( ratio is another way of writing a fraction) is greater than the right side. So we should expect that the answer is lesser. :)

The answer is 6.

If we would write it in a fraction form then convert is to its simplest term (ratio is another way of writing a fraction), the proportion will be 5/2.

In the missing proportion's case, the numerator is 15, so we should find a denominator such as when you convert them to lowest term, the answer would be the same than that of the original. So 15/6 = 5/2.

That is why the answer is 6.

NOTE: 
Logic can only be used when the numbers given are lesser, there is always a formula.

But I assure you, this is right! :)
