In order to find how many pieces of 1/3 feet rope you can make out of 7 feet rope, you have to divide 7 feet by 1/3 feet.

7/ (1/3) = 21 pieces

Therefore, you can make 21 1/3 – feet ropes.

Basically all you need to do is divide the total amount of rope you have by the amount of each piece so...

7 ÷ $\frac{1}{3}$
$7 * \frac{3}{1} = 21$ pieces
