It is not
If you multiply the denominator by 10 you get very close to the numerator. No need to do exact calculatio
999999/99990
99990X10=999900 which is only 99 less than the numerator.
I've run across several variants of the followingquestion:
\(\frac{10^8 - 10^2}{10^7 - 10^3}\)
Here is the approach I want totake:
\(\frac{10^2(10^6 - 1)}{10^3(10^4 - 1)}\)
But when I cancel the numerator/demoninator what I am left with is kind ofugly.
\(\frac{999999}{99990}\)
Is there something I am missing? Is there a better way?
