![\frac{20}{2} =10](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B2%7D%20%3D10)
![\frac{10}{2} =5](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B2%7D%20%3D5)
![\frac{5}{2} =2.5\\](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20%3D2.5%5C%5C)
![\frac{2.5}{2} =1.25](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7B2%7D%20%3D1.25)
