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

  • 4.310429537 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 = 4.310429537


Set up the second equation.

  • Number of decimal places repeating: 4

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


y = 4.310429537

10,000 × y = 10,000 × 4.310429537

10,000 × y = 43,104.29537

Get the same number of decimal places as for y:

10,000 × y = 43,104.295379537

Note: 43,104.295379537 = 43,104.29537


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.

10,000 × y - y = 43,104.295379537 - 4.310429537 ⇒

(10,000 - 1) × y = 43,104.295379537 - 4.310429537 ⇒

We now have a new equation:

9,999 × y = 43,099.98495


Solve for y in the new equation.

9,999 × y = 43,099.98495 ⇒

y = 43,099.98495/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 4.310429537

According to our calculations:

y = 43,099.98495/9,999

⇒ 4.310429537 = 43,099.98495/9,999


Get rid of the decimal places in the fraction above.

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

4.310429537 = (43,099.98495 × 100,000)/(9,999 × 100,000)

4.310429537 = 4,309,998,495/999,900,000

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

Multiply all the common prime factors by the lowest exponents.

GCF (3 × 5 × 11 × 26,121,203; 25 × 32 × 55 × 11 × 101) = 3 × 5 × 11


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


Divide both the numerator and the denominator by their GCF.

4,309,998,495/999,900,000 =

(3 × 5 × 11 × 26,121,203)/(25 × 32 × 55 × 11 × 101) =

((3 × 5 × 11 × 26,121,203) ÷ (3 × 5 × 11)) / ((25 × 32 × 55 × 11 × 101) ÷ (3 × 5 × 11)) =

26,121,203/(25 × 3 × 54 × 101) =

26,121,203/6,060,000


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.

26,121,203 ÷ 6,060,000 = 4, remainder = 1,881,203 ⇒

26,121,203 = 4 × 6,060,000 + 1,881,203 ⇒

26,121,203/6,060,000 =

(4 × 6,060,000 + 1,881,203) / 6,060,000 =

(4 × 6,060,000) / 6,060,000 + 1,881,203/6,060,000 =

4 + 1,881,203/6,060,000 =

4 1,881,203/6,060,000
