[SOLVED] Macro to delete rows based in the comparative of the columns between two sheets

Hi Guys,

I need to create a macro to delete the rows of the Master sheet based on the Report sheet.
The condition is, if the the number in the column A in the "Master" sheet is not in the first column in the "Report" sheet, the entire row regarding this number in the "Master" sheet should be deleted. Simple as that. :)

Any idea?

You can find the sheet attached below demonstrating that:

I appreciate guys!
Thank you! ;)
