Adding Numerators from fractions

[JrayK2]

I am adding numerators from fractions and currently using this formula:

=SUMPRODUCT(--(LEFT(0&I35:I38,FIND("/",0&I35:I38)-1)))

[TABLE="width: 89"]
<colgroup><col></colgroup><tbody>[TR]
[TD]25/20[/TD]
[/TR]
[TR]
[TD]20/20[/TD]
[/TR]
[TR]
[TD]19/20[/TD]
[/TR]
[TR]
[TD]19/20[/TD]
[/TR]
</tbody>[/TABLE]
83

I want my formula to cap out at the denominator however, for example on my first cell IF numerator is more than denominator, use denominator.
Can anyone help?

Hi,

Can you explain a bit further by giving one more example as to exactly what you need help with?

Thanks

Say I have 25/20, 25/20, 10/20, 10/20.

With the current formula I would get 70.
But I don't want to add the numerator past 100%, or greater than denominator. I'm looking to get 60 as result.

Here's a UDF you can try with an example using your data shown below.

Function SumTopExcept(R As Range) As Double
'sums numerators of cells containing fractions except if numerator > denominator in any cell,
'the denominator is used in the sum.
Dim c As Range, Parts As Variant, S As Double
For Each c In R
    If InStr(c.Value, "/") Then
        Parts = Split(c.Value, "/")
        If Parts(0) > Parts(1) Then
            S = S + Val(Parts(1))
        Else
            S = S + Val(Parts(0))
        End If
    End If
Next c
SumTopExcept = S
End Function

=MAX(SUMPRODUCT(--(LEFT(0&I35:I38,FIND("/",0&I35:I38)-1))), 20) should do what you want.

or
=MAX(SUMPRODUCT(--(LEFT(0&I35:I38,FIND("/",0&I35:I38)-1))), MID(I35, 1+ FIND("/",I35&"/"),255)+0)
