How to add total quantity of a score after the changing score Int?

Pardon me if I wasn't understandable with my question header, but I want to add "/12" after my score that I'm showing on the canvas.

Note that I was following the project "Roll a Ball" on the unity website and just wanted to make this small tweak where I show the total number of collectibles along with the currently collected. Something like "Collected: n/12" "n" being the current score.

I'm completely new hear, so pardon me again if I wasn't understandable. I lack the knowledge jargon too.

Here's the whole code where I've put the scoring text:

 using UnityEngine.UI;
 using System.Collections;
 
 public class PlayerController : MonoBehaviour {
 
     public float speed;
     public Text countText;
     public Text winText;
     public Text escapeInfo;
 
     private Rigidbody rb;
     private int count;
     private string total;
 
     void Start ()
     {
         rb = GetComponent<Rigidbody>();
         count = 0;
         SetCountText ();
         winText.text = "";
         escapeInfo.text = "";
     }
 
     void Update ()
     {
         if (Input.GetKey (KeyCode.Escape))
             Application.Quit ();
     }
 
     void FixedUpdate ()
     {
         float moveHorizontal = Input.GetAxis ("Horizontal");
         float moveVertical = Input.GetAxis ("Vertical");
     
         Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
         
         rb.AddForce (movement * speed);
     }
 
     void OnTriggerEnter(Collider other)
     {
         if (other.gameObject.CompareTag("Pick Up"))
         {
             other.gameObject.SetActive (false);
             count = count + 1;
             SetCountText ();
         }
     }
     void SetCountText ()
     {
         countText.text = "Collect: " + count.ToString ();
         if (count >= 12)
         {
             winText.text = "You Win";
             escapeInfo.text = "Press "Esc" to Exit";
         }
     }
 }
