\( 1 \leftarrow \begin{array}{llll}\text { a. } \frac{2}{5} & \text { b. } 1.50 & \text { c. } 0.25 & \text { d. } 30 \%\end{array} \) \( \begin{array}{l}\frac{2}{5}=\square \text { (Type a simplified fraction.) }\end{array} \)

Did you know that \(\frac{2}{5}\) is a fraction that represents a part of a whole? In this case, you can simplify \(\frac{2}{5}\) itself because it is already in its simplest form! However, when you look at it, it’s equivalent to 0.4 in decimal form, which can help in real-world situations like measuring ingredients in a recipe or calculating scores! If you're ever unsure about simplifying fractions, a common mistake is misidentifying factors. Remember, the greatest common factor (GCF) of the numerator and denominator is essential for simplification. For \(\frac{2}{5}\), since they share no common factors other than 1, it stays \(\frac{2}{5}\). Keep practicing, and you'll slice through fractions like a pro!
