A very good day to everyone. I have a perplexing question here:

$\displaystyle 13^-1 = 0.076923$. Without using a calculator, express 6 as a percentage of 26 to 3 places after the decimal.

I know that $\displaystyle 13^-1$ can be morphed into $\displaystyle \dfrac{1}{13}$, but how can it be applied to solve this question?

Any help is appreciated. Thank you so much!
