When a rope is used to wind a tree for five weeks, there is one sixth of a meter left, and when a third of the rope is used to wind it for one week, there is five sixth of a meter left. How many meters are the length of the rope and the circumference of the tree?

So how many meters are left around the tree with a rope?

5/6×3=5/2 (meter)

The difference between five turns and three turns:

5/2- 1/6=7/3 (m)

The circumference of this tree is:

7/3÷2=7/6 (meter)

Rope length:

7/6×5+ 1/6=6 (m)

A: The circumference of the tree is 7/6 meters, and the length of the rope is 6 meters.
