I would like to combine two columns into one and separate by a '/' using SQL statement

Currently, I could only do this.

```
Select A.Marks, Q.NoOfAnsBox FROM AnswerTable AS A INNER JOIN QuestionTable AS 
Q WHERE A.QuestionID = Q.QuestionID

```

With the output:

```
Marks NoOfAnsBox    
3     5    
2     5

```

May I know if it is possible to output it as one column as follows? 

```
Marks    
3/5    
2/5

```

I tried convert the integers into string and perform concatenation but failed to obtain the desired result

```
Select (CONVERT(A.Marks, Char(50)) + '/' + Convert(Q.NoOfAnsBox,Char(50))) As     
Marks FROM AnswerTable AS A INNER JOIN QuestionTable AS Q WHERE A.QuestionID = 
Q.QuestionID

```

```
Marks    
8    
7

```
