Question

Julian is mixing drops of food coloring to create green frosting for a cake. He uses 18 drops of yellow dye and 12 drops of blue dye. Find the ratio of drops of blue dye to total drops of dye. Express as a simplified ratio.

Answer 1

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
