8. \( \frac{5}{12}+\frac{5}{8} \)

To add \( \frac{5}{12} + \frac{5}{8} \), you first need a common denominator. The least common multiple of 12 and 8 is 24. Now, convert the fractions: \( \frac{5}{12} = \frac{10}{24} \) and \( \frac{5}{8} = \frac{15}{24} \). Now, add them together: \( \frac{10}{24} + \frac{15}{24} = \frac{25}{24} \). This can also be expressed as \( 1 \frac{1}{24} \). This fraction can also remind you of the importance of knowing how to find least common multiples—not only is it crucial for adding fractions, but it's a skill that pops up in various math disciplines, from algebra to even some geometry problems.
