[tex]\bf \begin{cases}
25\frac{1}{2}\implies \cfrac{25\cdot 2+1}{2}\implies \cfrac{51}{2}\\\\
26\frac{3}{8}\implies \cfrac{26\cdot 8+3}{8}\implies \cfrac{211}{8}
\end{cases}
26\frac{3}{8}\quad -\quad 25\frac{1}{2}\implies \cfrac{211}{8}-\cfrac{51}{2}
\\\\\\
LCD\implies 8\implies \cfrac{211-204}{8}\implies \boxed{\cfrac{7}{8}}[/tex]
Answer with explanation:
Length of Kitchen Shelf is equal to [tex]26\frac{3}{8}[/tex]
Length measured by Mrs. Hernanadez is equal to [tex]25\frac{1}{2}[/tex]
Error in Measurement
=Actual Length of Kitchen Shelf - Length measured by Mrs. Hernanadez
[tex]=26\frac{3}{8} -25\frac{1}{2}\\\\=\frac{26 \times 8+3}{8} -\frac{25 \times 2+1}{2}\\\\=\frac{211}{8}-\frac{51}{2}\\\\=\frac{211 -204}{8}\\\\=\frac{7}{8}[/tex]
⇒Her calculation is affected by a Length of 0.875 inches.
