2. Write the mixed repeating (recurring) decimal number as a proper fraction.

  • 0.06748 can be written as a proper fraction.

  • The numerator is smaller than the denominator.

Set up the first equation.

  • Let y equal the decimal number:

  • y = 0.06748


Set up the second equation.

  • Number of decimal places repeating: 4

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


y = 0.06748

10,000 × y = 10,000 × 0.06748

10,000 × y = 674.86748


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 = 674.86748 - 0.06748 ⇒

(10,000 - 1) × y = 674.86748 - 0.06748 ⇒

We now have a new equation:

9,999 × y = 674.8


Solve for y in the new equation.

9,999 × y = 674.8 ⇒

y = 674.8/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.06748

According to our calculations:

y = 674.8/9,999

⇒ 0.06748 = 674.8/9,999


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

0.06748 = (674.8 × 10)/(9,999 × 10)

0.06748 = 6,748/99,990


3. Reduce (simplify) the fraction above:
6,748/99,990
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).

6,748 = 22 × 7 × 241

99,990 = 2 × 32 × 5 × 11 × 101

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

Multiply all the common prime factors by the lowest exponents.

GCF (22 × 7 × 241; 2 × 32 × 5 × 11 × 101) = 2


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


Divide both the numerator and the denominator by their GCF.

6,748/99,990 =

(22 × 7 × 241)/(2 × 32 × 5 × 11 × 101) =

((22 × 7 × 241) ÷ 2) / ((2 × 32 × 5 × 11 × 101) ÷ 2) =

(2 × 7 × 241)/(32 × 5 × 11 × 101) =
