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

  • 1.0666668 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 = 1.0666668


Set up the second equation.

  • Number of decimal places repeating: 2

  • Multiply both sides of the first equation by 102 = 100


y = 1.0666668

100 × y = 100 × 1.0666668

100 × y = 106.66668

Get the same number of decimal places as for y:

100 × y = 106.6666868

Note: 106.6666868 = 106.66668


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.

100 × y - y = 106.6666868 - 1.0666668 ⇒

(100 - 1) × y = 106.6666868 - 1.0666668 ⇒

We now have a new equation:

99 × y = 105.60002


Solve for y in the new equation.

99 × y = 105.60002 ⇒

y = 105.60002/99

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 1.0666668

According to our calculations:

y = 105.60002/99

⇒ 1.0666668 = 105.60002/99


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 100,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

1.0666668 = (105.60002 × 100,000)/(99 × 100,000)

1.0666668 = 10,560,002/9,900,000


3. Reduce (simplify) the fraction above:
10,560,002/9,900,000
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).

10,560,002 = 2 × 29 × 97 × 1,877

9,900,000 = 25 × 32 × 55 × 11

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

Multiply all the common prime factors by the lowest exponents.

GCF (2 × 29 × 97 × 1,877; 25 × 32 × 55 × 11) = 2


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


Divide both the numerator and the denominator by their GCF.

10,560,002/9,900,000 =

(2 × 29 × 97 × 1,877)/(25 × 32 × 55 × 11) =

((2 × 29 × 97 × 1,877) ÷ 2) / ((25 × 32 × 55 × 11) ÷ 2) =

(29 × 97 × 1,877)/(24 × 32 × 55 × 11) =

5,280,001/4,950,000


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.

5,280,001 ÷ 4,950,000 = 1, remainder = 330,001 ⇒

5,280,001 = 1 × 4,950,000 + 330,001 ⇒

5,280,001/4,950,000 =

(1 × 4,950,000 + 330,001) / 4,950,000 =

(1 × 4,950,000) / 4,950,000 + 330,001/4,950,000 =

1 + 330,001/4,950,000 =

1 330,001/4,950,000
