To find out how much of the sandwich is left, subtract the amount eaten from the total length: $5 \frac{7}{8} - 3 \frac{3}{5}$. Convert to improper fractions: $\frac{47}{8} - \frac{18}{5}$. Find a common denominator (40): $\frac{235}{40} - \frac{144}{40} = \frac{91}{40}$, which simplifies to $2 \frac{11}{40}$.
