title: how to fix report numbering in latex
body: <p>I am using latex to write my thesis and it has the following numbering structure which is quite confusing when I make reference to previous chapters. For example, if am in chapter 3 and want to reference a subsection in chapter 2, I use section \ref{section 1} and it's not clear which section 1 I want (chapter 1 or 2).</p>
  <p><a href="https://i.stack.imgur.com/7QBne.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7QBne.png" alt="enter image description here" /></a></p>
  <p>So, how do I change the above like the image below</p>
  <p><a href="https://i.stack.imgur.com/cV61n.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cV61n.png" alt="enter image description here" /></a></p>
  <p>Below is the code in my header then inside the document I use \chapter, \section and \subsection to distinguish them.</p>
