I need to replicate a forumula in Excel which displays a ratio, being a sum of values based on certain criteria (in this case the number of items that failed in the Outcome column of a table) then effectively joins the result using &"/"& to the sum of all values in the same column.  So result in this case is not presented as a percentage (which would be rather more straightforward!) but e.g. 16/3,609.  This is the preferred presentation for the user as I suppose it provides more context than .44% necessarily would.

Use:

New measure =
VAR _Result = FORMAT([measure1], "Standard")  & "/" &  FORMAT([measure2], "Standard")
RETURN
SWITCH(TRUE(),

ISBLANK([measure1], BLANK(),
[measure1] = 0, BLANK(),

ISBLANK([measure2], BLANK(),
[measure2] = 0, BLANK(),
_Result)

You can do the same in DAX using the FORMAT function to convert numbers to whatever format you'd like.

Ratio = FORMAT ( [Numerator], "#,##0" ) & "/" & FORMAT ( [Denominator], "#,##0" )
