Answer:
3 parts
Step-by-step explanation:
This is just ratios. We know that red paint:white paint is equal to 2:1. Therefore we just have to substitute the values in.
Red paint = 6, so
6: White paint (=1)
Meaning that all we have to do is divide 6 by 2 (to find the value of one part), giving us 3 parts.
