Calculator results based on % or max points

Hi! This is probably a simple question, but I can't figure it out... I set up a calculator based on 14 questions. Every answer has a value of 1 to 5, so the max value for 14 questions is 196. How can I create 5 results, based on a percentage? So, result 1 = max 39,2 points (20%), result 2 = max 78,4 (40%), etc. etc. Can you help me with this please? Thanks in advance!
