I'm hoping someone can help with this.

I'm trying to sum all the numbers on the left of a '/' and the the numbers
on the right of the same.

Example:
22/55
0/7
1/125
216/0

I trying to find a way to make the sumproduct provide the result of...
239/187.

So far for the right side I have...

=SUMPRODUCT(--(MID(R2:R4,FIND("/",R2:R4,1)+1,3)))

.... But I can't seem to get the Left side to work.


Thanks In Advance.
