2. Write the mixed repeating (recurring) decimal number as a proper fraction.

  • 0.0462189 can be written as a proper fraction.

  • The numerator is smaller than the denominator.

Set up the first equation.

  • Let y equal the decimal number:

  • y = 0.0462189


Set up the second equation.

  • Number of decimal places repeating: 6

  • Multiply both sides of the first equation by 106 = 1,000,000


y = 0.0462189

1,000,000 × y = 1,000,000 × 0.0462189

1,000,000 × y = 46,218.9462189


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.

1,000,000 × y - y = 46,218.9462189 - 0.0462189 ⇒

(1,000,000 - 1) × y = 46,218.9462189 - 0.0462189 ⇒

We now have a new equation:

999,999 × y = 46,218.9


Solve for y in the new equation.

999,999 × y = 46,218.9 ⇒

y = 46,218.9/999,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.0462189

According to our calculations:

y = 46,218.9/999,999

⇒ 0.0462189 = 46,218.9/999,999


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.

0.0462189 = (46,218.9 × 10)/(999,999 × 10)

0.0462189 = 462,189/9,999,990


3. Reduce (simplify) the fraction above:
462,189/9,999,990

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

Multiply all the common prime factors by the lowest exponents.

GCF (3 × 7 × 13 × 1,693; 2 × 33 × 5 × 7 × 11 × 13 × 37) = 3 × 7 × 13


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


Divide both the numerator and the denominator by their GCF.

462,189/9,999,990 =

(3 × 7 × 13 × 1,693)/(2 × 33 × 5 × 7 × 11 × 13 × 37) =

((3 × 7 × 13 × 1,693) ÷ (3 × 7 × 13)) / ((2 × 33 × 5 × 7 × 11 × 13 × 37) ÷ (3 × 7 × 13)) =

1,693/(2 × 32 × 5 × 11 × 37) =
