[tex]\frac{5}{8} \text{ feet board is left }[/tex]
Solution:
Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project
To find: Board that was left
From given,
[tex]\text{Total length of board } =\frac{7}{8} \text{ feet }[/tex]
[tex]\text{Foot that was cut off } = \frac{1}{4} \text{ feet }[/tex]
Remaining feet of board is found by finding the difference between total length of board and foot that was cut off
[tex]\text{Reamining board } = \text{Total length of board - feet of board that was cut off}\\[/tex]
Substituting the values we get,
[tex]\text{Remaining board } = \frac{7}{8} - \frac{1}{4}\\\\\text{Remaining board } =\frac{7}{8} - \frac{1 \times 2}{4 \times 2}\\\\\text{Remaining board } =\frac{7}{8} -\frac{2}{8} = \frac{7-2}{8}\\\\\text{Remaining board } =\frac{5}{8}[/tex]
Thus [tex]\frac{5}{8}[/tex] feet board is left
