To find the factor by which the amount of red paint is multiplied to get the amount of white paint, we can analyze the given ratios:
-
In the first ratio, there are 2 parts of red paint and 6 parts of white paint.
- To find the multiplier: 6 (white) ÷ 2 (red) = 3.
-
In the second ratio, there are 4 parts of red paint and 12 parts of white paint.
- Again, the multiplier: 12 (white) ÷ 4 (red) = 3.
Thus, the amount of red paint is always multiplied by 3 to get the amount of white paint.
So the answer is: 3.
