The ratio of green food coloring to blue food coloring is 1: 2. we used 6 drops of blue. how many total drops of food coloring did we use

If the ratio of green to blue food coloring is 1:2 and 6 drops of blue was used, meaning that you basically multiplied 2 by 3 in order to get 6. Then the number of green drops would be 3 (1*3=3). 6+3=9
The total amount of drops of food coloring is then 9.

Hope this helps! (:

Ithink it is correct but just ask someone else but i am sure it it
