Final answer:
William cut a 4/5 foot piece of wood into 8 equal lengths. By dividing 0.8 (4/5 in decimal form) by 8, we find that each piece is 0.1 foot long.
Step-by-step explanation:
Calculating the Length of One Piece
William started with a length of wood measuring 4/5 of a foot and cut it into 8 equal lengths. To find the length of one piece, we divide the total length by the number of pieces.
Step 1: Convert the fraction 4/5 into decimal form, which is 0.8 feet.
Step 2: Divide 0.8 feet by 8 to find the length of one piece.
0.8 ÷ 8 = 0.1
Therefore, the length of one piece is 0.1 foot.
