0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.
![\begin{array}{ccll} \%&amount\\ \cline{1-2} \frac{1}{2}&250\\[1em] 100&x \end{array}\implies \cfrac{~~ \frac{1}{2}~~}{100}=\cfrac{250}{x}\implies \cfrac{1}{200}=\cfrac{250}{x}\implies x = 50000](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccll%7D%20%5C%25%26amount%5C%5C%20%5Ccline%7B1-2%7D%20%5Cfrac%7B1%7D%7B2%7D%26250%5C%5C%5B1em%5D%20100%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B~~%20%5Cfrac%7B1%7D%7B2%7D~~%7D%7B100%7D%3D%5Ccfrac%7B250%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B1%7D%7B200%7D%3D%5Ccfrac%7B250%7D%7Bx%7D%5Cimplies%20x%20%3D%2050000)
