I like solving this kind of thing by 'scaling up' the ratio, to avoid doing a ton of math.

1 gram in 0.8 liters
*10
10 grams in 8 liters
/8
10/8 grams in 1 liter
*3
30/8 grams in 3 liters

30/8 = 15/4, or answer (D).

We can use the following proportion:

1/(0.8) = n/3

3 = 0.8n

30 = 8n

n = 30/8 = 15/4
