(rounded off to max. 2 decimal places)


  • In other words:
  • Approximate to the desired number of decimal places...
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 0.5333333553.33%


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

  • 0.53333335 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 = 0.53333335


Set up the second equation.

  • Number of decimal places repeating: 8
  • Multiply both sides of the first equation by 108 = 100,000,000


y = 0.53333335


100,000,000 × y = 100,000,000 × 0.53333335


100,000,000 × y = 53,333,335.53333335


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 × y - y = 53,333,335.53333335 - 0.53333335


(100,000,000 - 1) × y = 53,333,335.53333335 - 0.53333335


We now have a new equation:


99,999,999 × y = 53,333,335


Solve for y in the new equation.

99,999,999 × y = 53,333,335 ⇒


y = 53,333,335/99,999,999


Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.53333335


According to our calculations:

y = 53,333,335/99,999,999


⇒ 0.53333335 = 53,333,335/99,999,999


3. Reduce (simplify) the fraction above:
53,333,335/99,999,999
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).

53,333,335 = 5 × 11 × 17 × 57,041


99,999,999 = 32 × 11 × 73 × 101 × 137



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

Multiply all the common prime factors by the lowest exponents.


GCF (5 × 11 × 17 × 57,041; 32 × 11 × 73 × 101 × 137) = 11



Divide both the numerator and the denominator by their GCF.

53,333,335/99,999,999 =


(5 × 11 × 17 × 57,041)/(32 × 11 × 73 × 101 × 137) =


((5 × 11 × 17 × 57,041) ÷ 11) / ((32 × 11 × 73 × 101 × 137) ÷ 11) =


(5 × 17 × 57,041)/(32 × 73 × 101 × 137) =
