Find Common Denominator: Find a common denominator for the fractions $\frac{1}{2}$ and $\frac{3}{8}$ . The least common denominator (LCD) for $2$ and $8$ is $8$ . Convert $\frac{1}{2}$ to a fraction with denominator $8$ : $\left(\frac{1}{2}\right) \times \left(\frac{4}{4}\right) = \frac{4}{8}$ . Now, add $\frac{4}{8}$ and $\frac{3}{8}$ together.
Convert to LCD: Add the fractions. $\newline$ $\frac{4}{8} + \frac{3}{8} = \frac{7}{8}$ .
