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

37.009398 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 = 37.009398


Set up the second equation.

Number of decimal places repeating: 4

Multiply both sides of the first equation by 104 = 10,000


y = 37.009398


10,000 × y = 10,000 × 37.009398


10,000 × y = 370,093.989398


Subtract the first equation from the second equation.

Having the same number of decimal places ...

The repeating pattern drops off by subtracting the two equations.


10,000 × y - y = 370,093.989398 - 37.009398


(10,000 - 1) × y = 370,093.989398 - 37.009398


We now have a new equation:


9,999 × y = 370,056


Solve for y in the new equation.

9,999 × y = 370,056 ⇒


y = 370,056/9,999


Let the result written as a fraction.



Write the number as a fraction.

According to our first equation:

y = 37.009398


According to our calculations:

y = 370,056/9,999


⇒ 37.009398 = 370,056/9,999


3. Reduce (simplify) the fraction above: 370,056/9,999
(to the lowest terms, to its simplest equivalent form, irreducible).

To reduce a fraction divide the numerator and the denominator by their greatest (highest) common factor (divisor), GCF.


Factor both the numerator and the denominator (prime factorization).

In exponential notation (an):


370,056 = 23 × 3 × 17 × 907


9,999 = 32 × 11 × 101



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

Multiply all the common prime factors by the lowest exponents.

GCF (23 × 3 × 17 × 907; 32 × 11 × 101) = 3



Divide both the numerator and the denominator by their greatest common factor, GCF.

370,056/9,999 =


(23 × 3 × 17 × 907)/(32 × 11 × 101) =


((23 × 3 × 17 × 907) ÷ 3) / ((32 × 11 × 101) ÷ 3) =


(23 × 17 × 907)/(3 × 11 × 101) =


123,352/3,333


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.


123,352 ÷ 3,333 = 37, remainder = 31 ⇒


123,352 = 37 × 3,333 + 31 ⇒


123,352/3,333 =


(37 × 3,333 + 31) / 3,333 =


(37 × 3,333) / 3,333 + 31/3,333 =


37 + 31/3,333 =


37 31/3,333


123,352/3,333: Equivalent fractions.
