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

  • 10.6666669 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 = 10.6666669


Set up the second equation.

  • Number of decimal places repeating: 2
  • Multiply both sides of the first equation by 102 = 100


y = 10.6666669


100 × y = 100 × 10.6666669


100 × y = 1,066.66669


Get the same number of decimal places as for y:


100 × y = 1,066.6666969


Note: 1,066.6666969 = 1,066.66669


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 = 1,066.6666969 - 10.6666669


(100 - 1) × y = 1,066.6666969 - 10.6666669


We now have a new equation:


99 × y = 1,056.00003


Solve for y in the new equation.

99 × y = 1,056.00003 ⇒


y = 1,056.00003/99


Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 10.6666669


According to our calculations:

y = 1,056.00003/99


⇒ 10.6666669 = 1,056.00003/99


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.

10.6666669 = (1,056.00003 × 100,000)/(99 × 100,000)


10.6666669 = 105,600,003/9,900,000


3. Reduce (simplify) the fraction above:
105,600,003/9,900,000
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).

105,600,003 = 3 × 35,200,001


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 (3 × 35,200,001; 25 × 32 × 55 × 11) = 3



Divide both the numerator and the denominator by their GCF.

105,600,003/9,900,000 =


(3 × 35,200,001)/(25 × 32 × 55 × 11) =


((3 × 35,200,001) ÷ 3) / ((25 × 32 × 55 × 11) ÷ 3) =


35,200,001/(25 × 3 × 55 × 11) =


35,200,001/3,300,000


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.

35,200,001 ÷ 3,300,000 = 10, remainder = 2,200,001 ⇒


35,200,001 = 10 × 3,300,000 + 2,200,001 ⇒


35,200,001/3,300,000 =


(10 × 3,300,000 + 2,200,001) / 3,300,000 =


(10 × 3,300,000) / 3,300,000 + 2,200,001/3,300,000 =


10 + 2,200,001/3,300,000 =


10 2,200,001/3,300,000
