2. Write the pure repeating (recurring) decimal number as an improper fraction.

  • 4.6669 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 = 4.6669


Set up the second equation.

  • Number of decimal places repeating: 4

  • Multiply both sides of the first equation by 104 = 10,000


y = 4.6669

10,000 × y = 10,000 × 4.6669

10,000 × y = 46,669.6669


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 = 46,669.6669 - 4.6669 ⇒

(10,000 - 1) × y = 46,669.6669 - 4.6669 ⇒

We now have a new equation:

9,999 × y = 46,665


Solve for y in the new equation.

9,999 × y = 46,665 ⇒

y = 46,665/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 4.6669

According to our calculations:

y = 46,665/9,999

⇒ 4.6669 = 46,665/9,999


3. Reduce (simplify) the fraction above:
46,665/9,999
to the lowest terms, to its simplest equivalent form, irreducible.

To reduce a fraction to the lowest terms divide the numerator and denominator by their greatest (highest) common factor (divisor), GCF.


Factor the numerator and denominator (prime factorization).

46,665 = 32 × 5 × 17 × 61

9,999 = 32 × 11 × 101

Calculate the greatest (highest) common factor (divisor), GCF.

Multiply all the common prime factors by the lowest exponents.

GCF (32 × 5 × 17 × 61; 32 × 11 × 101) = 32


» Calculate the greatest (highest) common factor (divisor), GCF, online calculator


Divide both the numerator and the denominator by their GCF.

46,665/9,999 =

(32 × 5 × 17 × 61)/(32 × 11 × 101) =

((32 × 5 × 17 × 61) ÷ 32) / ((32 × 11 × 101) ÷ 32) =

(5 × 17 × 61)/(11 × 101) =

5,185/1,111


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.

5,185 ÷ 1,111 = 4, remainder = 741 ⇒

5,185 = 4 × 1,111 + 741 ⇒

5,185/1,111 =

(4 × 1,111 + 741) / 1,111 =

(4 × 1,111) / 1,111 + 741/1,111 =

4 + 741/1,111 =

4 741/1,111
