Almost 60 years after taking my last math class, I discovered

how to turn a repeating decimal into its equivalent fraction.

- - Take the set of digits that repeats, no matter how many digits there are.

Write them as the numerator of a fraction.

- - For the denominator, write the same number of '9's.

- - If it's possible and you feel like it, simplify (reduce) the fraction.

You have 0.023 with the 23 (two digits) repeating forever.

- - Write the 23 (two digits) as the numerator.

- - Write 99 (two digits) as the denominator.

Now you have the fraction 23 / 99. It can't be reduced.

You actually had 0.0 ... before the repeating part. That just

means that the fraction has been divided by 10. The real

equivalent fraction is 23 / 990. (Which also can't be reduced.)

After so many years not knowing how to do it, this still blows my mind.

Just now, I punched " 23/990 "into my calculator, and stared in wonder

and amazement when " 0.023232323 " came up.
