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

  • 2.6669 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 = 2.6669


Set up the second equation.

  • Number of decimal places repeating: 4

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


y = 2.6669

10,000 × y = 10,000 × 2.6669

10,000 × y = 26,669.6669


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 = 26,669.6669 - 2.6669 ⇒

(10,000 - 1) × y = 26,669.6669 - 2.6669 ⇒

We now have a new equation:

9,999 × y = 26,667


Solve for y in the new equation.

9,999 × y = 26,667 ⇒

y = 26,667/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 2.6669

According to our calculations:

y = 26,667/9,999

⇒ 2.6669 = 26,667/9,999


3. Reduce (simplify) the fraction above:
26,667/9,999
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).

26,667 = 32 × 2,963

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 × 2,963; 32 × 11 × 101) = 32


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


Divide both the numerator and the denominator by their GCF.

26,667/9,999 =

(32 × 2,963)/(32 × 11 × 101) =

((32 × 2,963) ÷ 32) / ((32 × 11 × 101) ÷ 32) =

2,963/(11 × 101) =

2,963/1,111


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.

2,963 ÷ 1,111 = 2, remainder = 741 ⇒

2,963 = 2 × 1,111 + 741 ⇒

2,963/1,111 =

(2 × 1,111 + 741) / 1,111 =

(2 × 1,111) / 1,111 + 741/1,111 =

2 + 741/1,111 =

2 741/1,111
