Question

Carol is mixing pink paint. The ratio of red to white paint is 2:1. If carol uses 6 parts red paint. How much white paint does she need?

Answer 1

3 parts

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.
