Newbie alert here... I've looked around but can't seem to find an answer to my specific need. Which is this:

Suppose cell A2 contains a whole number that I've entered. I need cell B2 to calculate (and display) a range equal to say 50% - 60% of that number.

So if I enter 180 in A2, then I want B2 to display '90 - 108 ' (with spaces and dash!)

I then need only change A2 to have new results calculated and displayed in B2.

What formula would yield this result, please? Once I have the syntax I'll be able to edit it in order to deploy in multiple cells around my workbook.

Thanks for being here to help!
