100 / 7.45 = 13.422818791... (7.45 x that number = 100)
13.422818791... x 5.51 = 73.9597315436... (makes 5.51 equal to 7.45, if you know what I mean)
100 - 73.9597315436 = 26.040268456...% (difference between 100(7.45) and 73.95...(5.51)) 
Answer - 26.040268456%
This is my answer. I THINK it is correct but I do not guarantee it. enjoy!
