Average of multiple columns

I have a table called Request and the data looks like:

Req_ID    R1   R2   R3   R4   R5

R12673    2    5    3    7    10
R34721    3    5    2    1    8
R27835    1    3    8    5    6

Now I want to display the average of R1,R2,R3,R4 and R5

So I wrote a query like:

Select Req_ID, Avg(R1+R2+R3+R4+R5) as Average
from Request
Group by Req_ID

But I just get the sum of R1,R2,R3,R4 and R5 not the average? Where am I doing wrong.



If the data is stored as INT, you may want to try

Average = (R1 + R2 + R3 + R4 + R5) / 5.0
