How to convert a repeating decimal to a fraction?

There are several methods to convert repeating decimals to fractions. Here two common approaches:

Method 1: Algebraic Method
This method is more formal and works for all repeating decimals.

Let x = the repeating decimal.
Let n = the number of repeating digits.
Multiply both sides of the equation in (1) by 10ⁿ.
Subtract the equation from step (1) from the equation in step (3) to eliminate the repeating part.
Solve for x, expressing your answer as a fraction in its simplest form.

Method 2: Shortcut for Simple Repeating Decimals
This method works when the repeating part starts immediately after the decimal point.

Write the repeating digits as the numerator.
Write a denominator with the same number of 9s as there are repeating digits.
Simplify the fraction.

Example: Convert 0.121212… to a fraction
Numerator: 12
Denominator: 99 (two repeating digits)
Fraction: 12/99 = 4/33

Note:

If the decimal has a non-repeating part before the repeating part (like 0.1666…), you’ll need to use the algebraic method.
If there’s a whole number part (like 1.3434…), you can treat the decimal part separately and add it to the whole number at the end (1 + 34/99 = 133/99).

The following figure gives the steps for the algebraic method that will work for any repeating decimals.
