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

  • 74.2454 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 = 74.2454


Set up the second equation.

  • Number of decimal places repeating: 2

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


y = 74.2454

100 × y = 100 × 74.2454

100 × y = 7,424.54

Get the same number of decimal places as for y:

100 × y = 7,424.5454

Note: 7,424.5454 = 7,424.54


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 = 7,424.5454 - 74.2454 ⇒

(100 - 1) × y = 7,424.5454 - 74.2454 ⇒

We now have a new equation:

99 × y = 7,350.3


Solve for y in the new equation.

99 × y = 7,350.3 ⇒

y = 7,350.3/99

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 74.2454

According to our calculations:

y = 7,350.3/99

⇒ 74.2454 = 7,350.3/99


Get rid of the decimal places in the fraction above.

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

74.2454 = (7,350.3 × 10)/(99 × 10)

74.2454 = 73,503/990


3. Reduce (simplify) the fraction above:
73,503/990
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).

73,503 = 32 × 8,167

990 = 2 × 32 × 5 × 11

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

Multiply all the common prime factors by the lowest exponents.

GCF (32 × 8,167; 2 × 32 × 5 × 11) = 32


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


Divide both the numerator and the denominator by their GCF.

73,503/990 =

(32 × 8,167)/(2 × 32 × 5 × 11) =

((32 × 8,167) ÷ 32) / ((2 × 32 × 5 × 11) ÷ 32) =

8,167/(2 × 5 × 11) =

8,167/110


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.

8,167 ÷ 110 = 74, remainder = 27 ⇒

8,167 = 74 × 110 + 27 ⇒

8,167/110 =

(74 × 110 + 27) / 110 =

(74 × 110) / 110 + 27/110 =

74 + 27/110 =

74 27/110


8,167/110 ~ Equivalent fractions.

  • The above fraction cannot be reduced.
  • That is, it has the smallest possible numerator and denominator.

  • By expanding it we can build up equivalent fractions.

  • Multiply the numerator & the denominator by the same number.


Example 1. By expanding the fraction by 3.

8,167/110 = (8,167 × 3)/(110 × 3) = 24,501/330

Example 2. By expanding the fraction by 6.
