excel中的平均比率公式

Question

I've got two cells with the following data in them:

W7=2:1, W8=2:1

I am trying to get the average of these two cells but cannot figure it out since they are ratios. Obviously, the average should come out to 2:1 since (2:1 + 2:1) / 2 = 2:1 but it doesn't seem to be that simple when trying to calculate in Excel.

Is there a formula that can achieve this?

A little side note, the formula I am using to create the ratio is:

=ROUND((U8-M8)/(M8-V8),2)&":1"

So you can see, the 1 is just added and will be the same every time. That number is not actually being calculated.

Answer 1

If you can be happy with a result of 4:2 then,

=SUMPRODUCT(--REPLACE(W7:W8, FIND(":", W7:W8), LEN(W7:W8), TEXT(,)))&":"&SUMPRODUCT(--REPLACE(W7:W8, 1, FIND(":", W7:W8), TEXT(,)))

If you want to try and resolve the ratio down to x:1, VBA may be a better solution.

Per your recent addendum to the question, perhaps this will work.

=ROUND(SUMPRODUCT(--REPLACE(W7:W8, FIND(":", W7:W8), LEN(W7:W8), TEXT(,)))/COUNTA(W7:W8), 2)&":1"
