Hi
If you just want to replace your 10% with 10:1 (and 24% with 24:1) then you
can alter your formula and use a custom format.
If your total is in A2 and your 'score' is in B2, in C2 use
=(B2/A2)*100
and create a custom format of
#":1"
The result in the cell will still be 10 but will display as 10:1

Hope this helps.

Is there a formula that will automatically work out two numbers as a
ratio,
i.e. I want a sheet with numbers of sales calls, visits, sales, etc and to
automatically be able to see the no of calls to sales, calls to visits,
etc -
I want to express as, i.e. 10:1 rather than as 10%
