\begin{tabular}{l} Add. \\ \( \qquad \frac{5}{18}+\frac{3}{18} \) \\ \hline\end{tabular}

To solve \( \frac{5}{18}+\frac{3}{18} \), simply add the numerators since the denominators are the same. That means you get \( \frac{5 + 3}{18} = \frac{8}{18} \). You can then simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2. Thus, your final answer simplifies to \( \frac{4}{9} \). Now, isn't it interesting how fractions bring a piece of history? The use of fractions dates back to ancient Egypt, where they used unit fractions represented by real-world objects. They made calculations with these fractions for trade and land measurement, proving that math has been a vital part of human civilization for thousands of years! On the practical side, when adding fractions, always remember the golden rule: the denominators must be the same. Many people make the mistake of adding the fractions without aligning their denominators first, leading to incorrect answers. Keep that denominator in check, and you'll be golden!
