Find equivalent fractions to compare. Then, write \( >,< \), or \( = \). \[ \begin{array}{l}\frac{3}{10} ? \frac{4}{5} \\ \quad< \\ \quad=\end{array} \]

To compare the fractions \(\frac{3}{10}\) and \(\frac{4}{5}\), we can find a common denominator. The least common denominator (LCD) for 10 and 5 is 10. We can rewrite \(\frac{4}{5}\) as \(\frac{8}{10}\) (since \(4 \times 2 = 8\) and \(5 \times 2 = 10\)). Now we can compare: \[ \frac{3}{10} \quad \text{and} \quad \frac{8}{10} \] Since \(3 < 8\), it follows that: \[ \frac{3}{10} < \frac{4}{5} \] So, the final answer is: \[ \begin{array}{l}\frac{3}{10} < \frac{4}{5} \\ \quad< \\ \quad=\end{array} \]
