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

  • 0.227278 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 = 0.227278


Set up the second equation.

  • Number of decimal places repeating: 6

  • Multiply both sides of the first equation by 106 = 1,000,000


y = 0.227278

1,000,000 × y = 1,000,000 × 0.227278

1,000,000 × y = 227,278.227278


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.

1,000,000 × y - y = 227,278.227278 - 0.227278 ⇒

(1,000,000 - 1) × y = 227,278.227278 - 0.227278 ⇒

We now have a new equation:

999,999 × y = 227,278


Solve for y in the new equation.

999,999 × y = 227,278 ⇒

y = 227,278/999,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.227278

According to our calculations:

y = 227,278/999,999

⇒ 0.227278 = 227,278/999,999


3. Reduce (simplify) the fraction above:
227,278/999,999
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).

227,278 = 2 × 19 × 5,981

999,999 = 33 × 7 × 11 × 13 × 37

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

Multiply all the common prime factors by the lowest exponents.

But, the numerator and the denominator have no common factors.

GCF (2 × 19 × 5,981; 33 × 7 × 11 × 13 × 37) = 1


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


The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.
