The wood is 10/12 yard long.
She used 3/4 of the wood:
[tex] \dfrac{3}{4} \times \dfrac{10}{12} [/tex]
[tex] \dfrac{3}{4} \times \dfrac{2 \times 5}{3 \times 4} [/tex]
[tex] \dfrac{3}{8} \text { yard}[/tex]
Calculate yards left:
[tex] \dfrac{10}{12} - \dfrac{3}{8} [/tex]
[tex]= \dfrac{20}{24} - \dfrac{9}{24}[/tex]
[tex]= \dfrac{11}{24} \text { yard left}[/tex]
