5. What is the missing decimal in the box? \( \begin{array}{ll}\text { (1) } 10.508 & \text { (2) } 10.058 \\ \text { (3) } 10.52 & \text { (4) } 10.58\end{array} \)

To find the missing decimal in the box, we can analyze the given numbers: 1. \(10.508\) 2. \(10.058\) 3. \(10.52\) 4. \(10.58\) We can observe the numbers and look for a pattern or a logical sequence. - The first number, \(10.508\), has three decimal places. - The second number, \(10.058\), also has three decimal places. - The third number, \(10.52\), has two decimal places. - The fourth number, \(10.58\), also has two decimal places. It seems that the numbers can be grouped based on the number of decimal places. The first two numbers have three decimal places, while the last two have two decimal places. To find a missing number that fits in the sequence, we can look for a number that has two decimal places and falls between \(10.52\) and \(10.58\). The missing number could be \(10.56\), as it fits the criteria of having two decimal places and is between \(10.52\) and \(10.58\). Thus, the missing decimal in the box is: \[ \boxed{10.56} \]
