This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Yes, how do you not know this? @ashwin korade

It is not the question you are thinking about. There are unlimited 9s and you have to present it in the form of fraction.

Example:- If there is $0.7777777777......$, it would be represented as $\frac{7}{9}$.

$\frac {1}{1}$, if you let $\frac {1}{\infty}$ equal zero.

$0.99999999E = \frac {99999999E}{100000000}$.

I'm just guessing, but I would say $\frac{11}{11}=\frac{10}{11} + \frac{1}{11} = 0.\overline{90} + 0.\overline{09} = 0.\overline{99}$.

Mathematically, I don't see how this is different from any other fraction $\frac{p}{q}$ where $p=q$, but I think this is more a question of "aesthetics". Please tell me why or why not this is correct, I'm here to learn!

As far as I know, 0,99999999... is equal to 0,(9)= (9-0) / 9 = 1 , so every fraction p/q with p=q expresses 0,9999... .

- 5 years, 4 months ago

let us say that E= 0.99999999....... so, 10E = 9.99999999......... now, 10E - E = 9.9999999999...... - 0.9999999999...... hence, 9E=9 E= 1 this means that any fraction in the form p/q with p = q would be equal to 0.9999999......
