I have a group of numbers that already have a decimal in them. Example 68.77 when I try to format to make this a percentage I get this 6877%. How do I get it to keep the decimal in the number? I am looking for 68.77%
Type 100 anywhere on the sheet and copy it. Then select your numbers and hit paste special  divide Now they can all be turned into the correct percentage. 


If you want to maintain the numeric cell format for use in later computations, I might generate another column using the formula something like =b1/100.0 for all the cells in the new column. This assumes your problem column is in B. another suggestion, is that if this is derived from a formula, change the original formula to divide by 100 (or you could multiply by 0.01). 


If you want to display the whole number simply with a "%" at the end, try this format from the Excel format menu, 'custom' formats: "0.0\%);(0.0\%);0.0\%);@%)" Worked for me: 81.3582914270273 = 81.4%
