Need to change result without decimals in a "compound value result"

[edge37]

Hello! I need your assistance once again.
In the pics that I'm including, I need (L9) to calculate a grade over the total value of all grades, for that I'm using the formula:

=IF(A9="","",B9+C9+D9+E9+F9+G9+H9+I9&"/"&($B$40+$C$40+$D$40+$E$40+$F$40+$G$40+$H$40+$I$40))

.
In top pic it works well when in (C9) there's just a number that I typed, but, in bottom pic, when in (C9) I insert a formula

=5*(N9/100)

I need, I get the same result in that cell, but (L9) now show a number with 13 decimals. tried to format cell and chose number with 0 decimals, but the value do not change.

Is there any solution for this? I hope my description was clear enough

Thank you, friends.

Could this do the trick:

=IF(A9="","",ROUND(SUM(B9:I9),0)&"/"&ROUND(SUM($B$40:$I$40),0))

?
