Quizplus · Accepted Answer

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