Hey there!
Your question really does not provide much information that I need. But, from the information that you have provided, I would be more than happy to try to help you Alyssa.
So, 1 over 100 using "power of" by 10 and also using negative exponent's would look like the following.
![\left[\begin{array}{ccc}\boxed{\boxed{ (1-x^1^0)/(100-x^1^0)}} \end{array}\right]](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ehermngwdooe39pzl81gsodnvgwfthkdv5.png)
I hope this helps you!
