\begin{gathered} \text{Length of the board}=(5)/(6)\text{ ft} \\ \text{Length of one piece }=(5)/(16)\text{ ft} \\ \end{gathered}

The expression which is used to calculate the number of pieces that can be cut from the board is:


(5)/(6)/(5)/(16)

We solve this by changing the division sign to multiplication and taking the reciprocal of the second fraction.

Therefore:


\begin{gathered} (5)/(6)/(5)/(16)=(5)/(6)*(16)/(5) \\ =(16)/(6) \\ =2\text{ }(4)/(6) \\ =2(2)/(3)\text{ pieces} \end{gathered}

The carpenter can cut 2 2/3 pieces from the board.
