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

  • 0.525254 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 = 0.525254


Set up the second equation.

  • Number of decimal places repeating: 2

  • Multiply both sides of the first equation by 102 = 100


y = 0.525254

100 × y = 100 × 0.525254

100 × y = 52.5254

Get the same number of decimal places as for y:

100 × y = 52.525454

Note: 52.525454 = 52.5254


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 = 52.525454 - 0.525254 ⇒

(100 - 1) × y = 52.525454 - 0.525254 ⇒

We now have a new equation:

99 × y = 52.0002


Solve for y in the new equation.

99 × y = 52.0002 ⇒

y = 52.0002/99

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.525254

According to our calculations:

y = 52.0002/99

⇒ 0.525254 = 52.0002/99


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

0.525254 = (52.0002 × 10,000)/(99 × 10,000)

0.525254 = 520,002/990,000


3. Reduce (simplify) the fraction above:
520,002/990,000
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).

520,002 = 2 × 32 × 7 × 4,127

990,000 = 24 × 32 × 54 × 11

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

Multiply all the common prime factors by the lowest exponents.

GCF (2 × 32 × 7 × 4,127; 24 × 32 × 54 × 11) = 2 × 32


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


Divide both the numerator and the denominator by their GCF.

520,002/990,000 =

(2 × 32 × 7 × 4,127)/(24 × 32 × 54 × 11) =

((2 × 32 × 7 × 4,127) ÷ (2 × 32)) / ((24 × 32 × 54 × 11) ÷ (2 × 32)) =

(7 × 4,127)/(23 × 54 × 11) =

28,889/55,000
