Theory:

General rule for representing decimals on a number line:
Step 1: Let us first find on which two integers where the decimal number lie.

Step 2: Divide the length between those two integers into ten equal parts.

Step 3: Move as many steps you want from the preceding integer to the right.

Step 4: You will reach the decimal number on the number line.
Locate \(0.5\) on the number line.
 
Step 1: The decimal number \(0.5\) lies between \(0\) to \(1\).
 
Step 2: Divide the length between \(0\) to \(1\) into ten equal parts.
 
Step 3: Move five-step to the right from \(0\).
 
Step 4: The reached number in the number line is \(0.5\).
