Answer: 900 inch There is 3 ribbon in this question, Red ribbon(R), green ribbon(G) and purple ribbon(P). The relation would be 1. R= 9 inch 2. R= 1/10 G 3. P= 10 G
If you insert equation 1 into 2 then you will get: 9inch= 1/10G G= 90 inch
After that insert the new equation into equation 3: P= 10x 90 inch P= 900inch
