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

  • 22.28574 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 = 22.28574


Set up the second equation.

  • Number of decimal places repeating: 4

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


y = 22.28574

10,000 × y = 10,000 × 22.28574

10,000 × y = 222,857.48574


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 = 222,857.48574 - 22.28574 ⇒

(10,000 - 1) × y = 222,857.48574 - 22.28574 ⇒

We now have a new equation:

9,999 × y = 222,835.2


Solve for y in the new equation.

9,999 × y = 222,835.2 ⇒

y = 222,835.2/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 22.28574

According to our calculations:

y = 222,835.2/9,999

⇒ 22.28574 = 222,835.2/9,999


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.

22.28574 = (222,835.2 × 10)/(9,999 × 10)

22.28574 = 2,228,352/99,990

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

Multiply all the common prime factors by the lowest exponents.

GCF (27 × 3 × 7 × 829; 2 × 32 × 5 × 11 × 101) = 2 × 3


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


Divide both the numerator and the denominator by their GCF.

2,228,352/99,990 =

(27 × 3 × 7 × 829)/(2 × 32 × 5 × 11 × 101) =

((27 × 3 × 7 × 829) ÷ (2 × 3)) / ((2 × 32 × 5 × 11 × 101) ÷ (2 × 3)) =

(26 × 7 × 829)/(3 × 5 × 11 × 101) =

371,392/16,665


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.

371,392 ÷ 16,665 = 22, remainder = 4,762 ⇒

371,392 = 22 × 16,665 + 4,762 ⇒

371,392/16,665 =

(22 × 16,665 + 4,762) / 16,665 =

(22 × 16,665) / 16,665 + 4,762/16,665 =

22 + 4,762/16,665 =

22 4,762/16,665
