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?

Respuesta :

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:)
3times 4 is 12 drops of yellow coloring so 4 times 4 is 16 drops
