Answer:
I believe it is 1/9 or 11.1%
Step-by-step explanation:
11/99 /(divided by) 11 = 1/9
1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)
so as a percent, it makes it 11.1% (repeating) or 11 % (which is a more exact solution)
now if you need a ratio, it would be 1:9
hope this helps :)
