Quizplus · Accepted Answer

To subtract fractions with different denominators, first find a common denominator, which in this case is 56 (the least common multiple of 8 and 7). Convert each fraction: $\frac{5}{8} = \frac{35}{56}$ and $\frac{3}{7} = \frac{24}{56}$. Subtracting these gives $\frac{35}{56} - \frac{24}{56} = \frac{11}{56}$.
