Constant Cell reference

[Manoharal]

Please advise:
I would like a cell reference to be constant. The calculation is like
this: a2+b2= c2. c2*a9%=d2. Now, when I go to the next row, I want the
a9% reference to be constant while c2 should carry on c3, c4, c5 and on.
i.e. the formula should go on like this- c2*a9%, c3*a9%, c4*a9%. I have
given the figure for percentage calculation in A9. what should be the formula?

You would need to use the F4 function key whilst editing in the cell and where you have A9, so it would show $A$9
