QUICK TIP: CONVERT THE NUMBER INTO PERCENTILE

If we want to add "%" in each cell in a column, we generally select home tab, then go to % and it converts the number in the following format.

1000%
3300%
3700%
1200%
1100%
4200%
2400%
2400%

Write 100 in a cell & copy itSelect the data which you want to format (In this case A1:A8)
Right click and go to Paste Special
Select divide
Press OK
Go to Home tab and select Percent Style
