There are three red, yellow and blue ribbons of the same length. Master Li cut a part from each of the three ribbons and connected them into a long ribbon 8 meters long (negligible at the joint). At this time, he found that the red ribbon cut off one-third of its original length, and the cut off part of the yellow ribbon was the same length as the remaining part of the blue ribbon. Do you know how many meters each ribbon is?
有红、黄、蓝三根同样长的彩带．李师傅从这三根彩带中各截取一部分，连接成一根8米长的长彩带(接头处忽略不计)．这时他发现，红彩带截去的是它原来的三分之一，黄彩带截去的部分和蓝彩带剩下的部分同样长．你知道原来每根彩带长多少米吗？
