A pom-pom manufacturer makes each of its pom-poms with 35% white strands (w), 25% blue strands (b), and 40% red strands (r). If each pom-pom has a total of 80 strands, how many of strands of each color are needed to make a pair of pom-poms? In this activity, you’ll work through this pom-pom problem step by step.

Part A

Write a proportion for the number of strands in each color to find how many strands are needed to make one pom-pom.

white strands: w/80 = ?/? blue strands: b/80 = ?/? red strands: r/80 = ?/?
