Answer
Total 9 drops of food coloring did we use
Step-by-step explanation:
Let the number be x.
As per the statement:
The ratio of green food coloring to blue food coloring is:
1 : 2
number drops of green = x
number drops of blue= 2x
It is also given that:
we used 6 drops of blue.
⇒
Divide both sides by 2 we have;
x = 3
We have to find how many total drops of food coloring did we use.
Total number of drops = x+2x = 3x
⇒Total number of drops = 3(3) = 9
Therefore, 9 total drops of food coloring did we use
