2. Write the mixed repeating (recurring) decimal number as an improper fraction.

  • 4.2323232326 can be written as an improper fraction.

  • The numerator is larger than or equal to the denominator.

Set up the first equation.

  • Let y equal the decimal number:

  • y = 4.2323232326


Set up the second equation.

  • Number of decimal places repeating: 2

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


y = 4.2323232326

100 × y = 100 × 4.2323232326

100 × y = 423.23232326

Get the same number of decimal places as for y:

100 × y = 423.2323232626

Note: 423.2323232626 = 423.23232326


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 = 423.2323232626 - 4.2323232326 ⇒

(100 - 1) × y = 423.2323232626 - 4.2323232326 ⇒

We now have a new equation:

99 × y = 419.00000003


Solve for y in the new equation.

99 × y = 419.00000003 ⇒

y = 419.00000003/99

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 4.2323232326

According to our calculations:

y = 419.00000003/99

⇒ 4.2323232326 = 419.00000003/99


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 100,000,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

4.2323232326 = (419.00000003 × 100,000,000)/(99 × 100,000,000)

4.2323232326 = 41,900,000,003/9,900,000,000


3. Reduce (simplify) the fraction above:
41,900,000,003/9,900,000,000
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).

41,900,000,003 = 78,229 × 535,607

9,900,000,000 = 28 × 32 × 58 × 11

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 (78,229 × 535,607; 28 × 32 × 58 × 11) = 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.


4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):

  • A mixed number = an integer number and a proper fraction, of the same sign.
  • Example 1: 2 1/5; Example 2: - 1 3/7.
  • A proper fraction = the numerator is smaller than the denominator.

41,900,000,003 ÷ 9,900,000,000 = 4, remainder = 2,300,000,003 ⇒

41,900,000,003 = 4 × 9,900,000,000 + 2,300,000,003 ⇒

41,900,000,003/9,900,000,000 =

(4 × 9,900,000,000 + 2,300,000,003) / 9,900,000,000 =

(4 × 9,900,000,000) / 9,900,000,000 + 2,300,000,003/9,900,000,000 =

4 + 2,300,000,003/9,900,000,000 =

4 2,300,000,003/9,900,000,000
