title: How would one calculate percent error between two ratios
body: <p>Let's say I have a 1:1 ratio and a 5:1 ratio which could also be interpreted as a 1:5 ratio. the fact that both of these ratios are valid but one is 5 while the other is 0.2 is the problem, because if we plug this into the percent error formula (|E−T|/|T|) we get both 80% and 400%. which would be correct? what are the rules for this? Right now I just need to figure out how to do this mathematically, this isn't a problem with the code.</p>
