Answer:
There are 9 knots tied in the rope.
Step-by-step explanation:
First, we need to convert 2/3 feet into a decimal. We can do this by dividing 2 by 3:
2 ÷ 3 = 0.66666667
Now that we have the decimal equivalent of 2/3 feet, we can divide the length of the rope by this distance:
6 ÷ 0.66666667 = 9 knots
Therefore, there are 9 knots tied in the rope.
