2. Write the pure repeating (recurring) decimal number as an improper fraction.
9,387.3858 can be written as an improper fraction.
- The numerator is larger than or equal to the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 9,387.3858
Set up the second equation.
- Number of decimal places repeating: 4
Multiply both sides of the first equation by 104 = 10,000
y = 9,387.3858
10,000 × y = 10,000 × 9,387.3858
10,000 × y = 93,873,858.3858
Subtract the first equation from the second one.
- Having the same number of decimal places ...
- The repeating pattern drops off by subtracting the two equations.
10,000 × y - y = 93,873,858.3858 - 9,387.3858 ⇒
(10,000 - 1) × y = 93,873,858.3858 - 9,387.3858 ⇒
We now have a new equation:
9,999 × y = 93,864,471
Solve for y in the new equation.
9,999 × y = 93,864,471 ⇒
y = 93,864,471/9,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 9,387.3858
According to our calculations:
y = 93,864,471/9,999
⇒ 9,387.3858 = 93,864,471/9,999
3. Reduce (simplify) the fraction above:
93,864,471/9,999

Factor the numerator and denominator (prime factorization).
93,864,471 = 3 × 4,159 × 7,523
9,999 = 32 × 11 × 101
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (3 × 4,159 × 7,523; 32 × 11 × 101) = 3
Divide both the numerator and the denominator by their GCF.
93,864,471/9,999 =
(3 × 4,159 × 7,523)/(32 × 11 × 101) =
((3 × 4,159 × 7,523) ÷ 3) / ((32 × 11 × 101) ÷ 3) =
(4,159 × 7,523)/(3 × 11 × 101) =
31,288,157/3,333
4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):
- A mixed number = an integer number and a proper fraction, of the same sign.
- Example 1: 2 1/5; Example 2: - 1 3/7.
- A proper fraction = the numerator is smaller than the denominator.
31,288,157 ÷ 3,333 = 9,387, remainder = 1,286 ⇒
31,288,157 = 9,387 × 3,333 + 1,286 ⇒
31,288,157/3,333 =
(9,387 × 3,333 + 1,286) / 3,333 =
(9,387 × 3,333) / 3,333 + 1,286/3,333 =
9,387 + 1,286/3,333 =
9,387 1,286/3,333
