Hello! I could really use some help with the below problem. I am unsure of how to make a common-size income statement. Any help is appreciated!

Use the income statement information to make a common-size income statement for all three years. You can find the statements here https://www.scribd.com/document/374135183/Pinnacle-Financials. Use the information to identify accounts for which you believe there is a concern about material misstatements.
