Answer:
length of piece cut off from the board was [tex]1\frac{5}{12}[/tex] feet.
Step-by-step explanation:
Board with Zoe has the length = [tex]5\frac{1}{4}[/tex] feet
≈ [tex]\frac{21}{4}[/tex] feet
Now she cut off a piece of length then the length of the board = [tex]3\frac{5}{6}[/tex] feet
≈ [tex]\frac{23}{6}[/tex] feet
Length of the piece of piece she cut off = [tex]\frac{21}{4}-\frac{23}{6}[/tex]
= [tex]\frac{63-46}{12}[/tex]
= [tex]\frac{17}{12}[/tex]
= [tex]1\frac{5}{12}[/tex] feet
Therefore, length of piece cut off from the board was [tex]1\frac{5}{12}[/tex] feet.
