To decorate a cake, you make a shade of green icing using 3 drops of yellow food coloring for every 4 drops of blue food coloring. If you use 12 drops of yellow food coloring, how many drops of blue food coloring would you need?
that would be 16 because if you use 3 drops for every 4 drops and right now you need 12 that means you have to multiply 4 by 4 and that is 16.Hope this helps:)
