Avoiding decimals, Dividing both 125 and 550 by 25, it becomes 5/22
[tex]125|5\\.\ 25|5\\.\ \ 5|5\\.\ \ 1|\\125=5\times5\times5\\\\550|5\\110|5\\.\ 22|2\\.\ 11|11\\.\ \ 1|\\550=5\times5\times2\times11\\\\\frac{125}{550}=\frac{\not5^1\times\not5^1\times5}{\not5_1\times\not5_1\times2\times11}=\frac{5}{2\times11}=\frac{5}{22}[/tex]
