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.
[tex] \left[\begin{array}{ccc}\boxed{\boxed{ \frac{1-x^1^0}{100-x^1^0}}} \end{array}\right] [/tex]
I hope this helps you!
