Lesson 2: Visualize equivalent ratios

# Simplify a ratio from a tape diagram

In this problem, we have a mixture of yellow and red paint. There are 12 parts yellow and 8 parts red. We want to find the ratio of red paint to the total paint in the mixture. To do this, we add the parts of red and yellow paint together (8 + 12 = 20). The ratio of red paint to total paint is 8:20.  Created by Sal Khan.
