Answer:
13 pieces
Explanation:
To find out how many pieces can be cut from the big board, we need to divide the length of the board by the length of one piece.
The length of one piece is 1 and 1/3 feet. We can write this as a fraction as follows:
1 and 1/3 feet = 1 + 1/3 feet = 4/3 feet
Therefore, the number of pieces that can be cut from the board is:
18 feet / (4/3 feet/piece) = 18 feet × (3/4 feet/piece)
= 13.5 pieces
So, the person can cut 13.5 pieces from the 18-foot board. However, since we can't have a fraction of a piece in reality, the person can cut 13 whole pieces from the 18-foot board.
