devlian [24]

Answer:

The ratio would be 2:5

Explanation:

The ratio of drops of blue dye to total drops of dye is got by dividing drops of blue dye  (12) by total drops, which is the sum of blue and yellow drops (12+18):

\displaystyle\frac{12}{12+18}=\frac{12}{30}

Once we simplify the fraction by dividing both top and bottom by 6, we would get:

\displaystyle\frac{2}{5}

Therefore, the ratio of drops of blue dye to total drops of dye is:  2:5
