I know how to write the formula to calculate each individual cell but I don't know how to write a formula that can be copied and used among all three cells.

I hope this isn't homework.

in C2
=B2/B$6*100
and copy down

OK, thank you Special-K. I couldn't think of how to fix the row, I was forgetting the "$". Thanks again.
