3. \( \frac{1}{2}+\frac{7}{8}= \)

To add \( \frac{1}{2} \) and \( \frac{7}{8} \), we first need a common denominator. The least common multiple of 2 and 8 is 8. Convert \( \frac{1}{2} \) to eighths: \( \frac{1}{2} = \frac{4}{8} \). Now, you can add: \( \frac{4}{8} + \frac{7}{8} = \frac{11}{8} \) or \( 1 \frac{3}{8} \). In the world of fractions, mastering addition and finding common denominators is like piecing together a puzzle! When working with different fractions, always look for the least common multiple. This not only simplifies your calculation but also boosts your number-crunching skills for future math adventures!
