Question

The ratio of green food coloring to blue food coloring is 1 to 2 if we you six drops of blue how many drops of brain do we need

Answer 1

I think the question is asking how many drops of green.

If for every 1 drop of green you need 2 drops of blue, then you only need 3 drops of green for 6 blue.

Here are the ratios so you can see that they are equivalent.

1 g/2b = 2g/4b = 3g/6b
