Hi Luis,

To delete part of the content on multiple cells in Excel, you can use the "Find and Replace" feature. Here are the steps:

1. Select the range of cells that you want to modify.
2. Press "Ctrl + H" on your keyboard to open the "Find and Replace" dialog box.
3. In the "Find what" field, enter the text that you want to remove. For example, if you want to remove everything before the percentage numbers, enter "* " (without the quotes and with a space after the asterisk).
4. Leave the "Replace with" field blank.
5. Click on "Replace All" to remove the text from all the selected cells.

If you want to leave the first set of numbers and delete the comma space percentage numbers, you can use the "Text to Columns" feature. Here are the steps:

1. Select the range of cells that you want to modify.
2. Click on the "Data" tab in the ribbon.
3. Click on "Text to Columns" in the "Data Tools" group.
4. In the "Convert Text to Columns Wizard" dialog box, select "Delimited" and click on "Next".
5. In the "Delimiters" section, select "Comma" and "Space" and click on "Next".
6. In the "Data preview" section, select the second column and select "Do not import column (skip)" in the "Column data format" section.
7. Click on "Finish" to split the text into two columns.
8. Delete the second column to remove the comma space percentage numbers.
