2. Write the pure repeating (recurring) decimal number as a proper fraction.
0.14285714289 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 = 0.14285714289
Set up the second equation.
- Number of decimal places repeating: 11
Multiply both sides of the first equation by 1011 = 100,000,000,000
y = 0.14285714289
100,000,000,000 × y = 100,000,000,000 × 0.14285714289
100,000,000,000 × y = 14,285,714,289.14285714289
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.
100,000,000,000 × y - y = 14,285,714,289.14285714289 - 0.14285714289 ⇒
(100,000,000,000 - 1) × y = 14,285,714,289.14285714289 - 0.14285714289 ⇒
We now have a new equation:
99,999,999,999 × y = 14,285,714,289
Solve for y in the new equation.
99,999,999,999 × y = 14,285,714,289 ⇒
y = 14,285,714,289/99,999,999,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.14285714289
According to our calculations:
y = 14,285,714,289/99,999,999,999
⇒ 0.14285714289 = 14,285,714,289/99,999,999,999

14,285,714,289/99,999,999,999
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).
14,285,714,289 = 3 × 7 × 11 × 61,842,919
99,999,999,999 = 32 × 21,649 × 513,239
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (3 × 7 × 11 × 61,842,919; 32 × 21,649 × 513,239) = 3
Divide both the numerator and the denominator by their GCF.
14,285,714,289/99,999,999,999 =
(3 × 7 × 11 × 61,842,919)/(32 × 21,649 × 513,239) =
((3 × 7 × 11 × 61,842,919) ÷ 3) / ((32 × 21,649 × 513,239) ÷ 3) =
(7 × 11 × 61,842,919)/(3 × 21,649 × 513,239) =
