Q.Kim finds a 1-meter tree branch and marks it off in thirds and fifths. She then breaks the branch along all the markings and removes one piece of every distinct length. What fraction of the original branch remains?

what fraction of the original branch remains??--- i tried doing this by taking a LCM of 3 and 5... divided the line into 7 parts...see the divisions---
1. 1/5(3/15),
2. 1/3(5/15),
3. 2/5(6/15),
4. 3/5(9/15),
5. 2/3(10/15),
6, 4/5(12/15).

what fraction of the original branch remains??

every part of the branch is original right ??

it means how much of the original is left after we remove the pieces we are supposed to remove..
