Assume you want to increase by 10%. If you want to do this in another
cell:
B1: =A1 * (1 + 10%)
or, equivalently
B1: =A1 * 1.1
To do it in-place:
Enter 1.1 in a cell. Copy it. Select your cell(s) to be increased.
Choose Edit/Paste Special, selecting the Values and Multiply radio
buttons. Click OK.
Enter 1.15 in a blank cell. Copy the entire cell (not the value - e.g.,
don't enter edit mode before you copy). Select the cells with numbers
you want to increase. Choose Edit/Paste Special. Click on the Values and
Multiply radio buttons to select them, then click OK.
got none but the last feature to enter 1.15 in cell then copy and selec
past special and choose the values and multiply then ok...solved th
matter. thanks for the reply
