You were right the first time - 30/20/3000 is the same as 1.5/1/150
here it is proven out -
3000/150 is 20
1.5x20=30 (a)
1x20=20(b)

Ok, so whats the correct ratio for the question I asked?
(A)1.5(B)1 (3000ml water)150
what are my (A) and (B) dilutions?
I'm arriving at my answer by dividing the 3000ml by 151.
