Solve the Fraction Addition: 2/9 + 1/2

Since 9 and 2 share no common factors, their LCD is simply $9 \times 2 = 18$. For larger numbers, list multiples or use prime factorization.

Fractions represent parts of a whole. $\frac{2}{9}$ means 2 ninths, and $\frac{1}{2}$ means 1 half. You can't add different-sized pieces directly - they need to be the same size first!

Always check if your answer can be simplified! For $\frac{13}{18}$, since 13 is prime and doesn't divide 18, it's already in lowest terms.

Don't worry! The LCD might seem large, but it ensures accurate addition. For $\frac{2}{9} + \frac{1}{2}$, using LCD = 18 gives the correct answer $\frac{13}{18}$.

While possible, exact fraction answers are usually preferred in math class. Converting $\frac{2}{9}$ to decimal gives 0.222..., which is harder to work with than the fraction form.
