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

  • 4.2323232327 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 = 4.2323232327


Set up the second equation.

  • Number of decimal places repeating: 2

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


y = 4.2323232327

100 × y = 100 × 4.2323232327

100 × y = 423.23232327

Get the same number of decimal places as for y:

100 × y = 423.2323232727

Note: 423.2323232727 = 423.23232327


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 = 423.2323232727 - 4.2323232327 ⇒

(100 - 1) × y = 423.2323232727 - 4.2323232327 ⇒

We now have a new equation:

99 × y = 419.00000004


Solve for y in the new equation.

99 × y = 419.00000004 ⇒

y = 419.00000004/99

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 4.2323232327

According to our calculations:

y = 419.00000004/99

⇒ 4.2323232327 = 419.00000004/99


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.

4.2323232327 = (419.00000004 × 100,000,000)/(99 × 100,000,000)

4.2323232327 = 41,900,000,004/9,900,000,000


3. Reduce (simplify) the fraction above:

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

Multiply all the common prime factors by the lowest exponents.

GCF (22 × 33 × 5,953 × 65,171; 28 × 32 × 58 × 11) = 22 × 32


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


Divide both the numerator and the denominator by their GCF.

41,900,000,004/9,900,000,000 =

(22 × 33 × 5,953 × 65,171)/(28 × 32 × 58 × 11) =

((22 × 33 × 5,953 × 65,171) ÷ (22 × 32)) / ((28 × 32 × 58 × 11) ÷ (22 × 32)) =

(3 × 5,953 × 65,171)/(26 × 58 × 11) =

1,163,888,889/275,000,000


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.

1,163,888,889 ÷ 275,000,000 = 4, remainder = 63,888,889 ⇒

1,163,888,889 = 4 × 275,000,000 + 63,888,889 ⇒

1,163,888,889/275,000,000 =

(4 × 275,000,000 + 63,888,889) / 275,000,000 =

(4 × 275,000,000) / 275,000,000 + 63,888,889/275,000,000 =

4 + 63,888,889/275,000,000 =
