The relationship between the pairs can be understood in terms of ratios. In the first pair, 22 is to 555 as 55 is to 1000 because both pairs represent a proportional increase. Specifically, if you multiply 22 by 25.23, you get approximately 555, and if you multiply 55 by 18.18, you get 1000. This shows that both pairs maintain a consistent scaling factor.
