\( \begin{array}{lllll}\text { 3. Write these decimals in order from least to greatest. } & 0.403 & 0.034 & 0.340\end{array} \)

To arrange the decimals from least to greatest, start by comparing them. The smallest number here is \(0.034\), followed by \(0.340\), and the largest is \(0.403\). So, the order is \(0.034\), \(0.340\), \(0.403\). And voilà! Decimal sorting can be fun – like putting together a puzzle to see which piece fits where! Always remember to align the decimal points; it makes comparison much easier!
