How to return a blank field to a cell when a formula is working a number

Probably a really easy solution.

I’m working with a sheet that has a simple division of two numbers to return the difference as a percentage. In this case: =O12/K12

Now if O12 and K12 are empty the cell returns a value of 0.00%. How can I change the formula so it just stays blank if there is no data in O12 and K12 please?

Any help would be amazing!

Thanks
Ryan

>Solution :

try:

=IFERROR(1/(1/(O12/K12)))
