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

  • 0.53333333338 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 = 0.53333333338


Set up the second equation.

  • Number of decimal places repeating: 4

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


y = 0.53333333338

10,000 × y = 10,000 × 0.53333333338

10,000 × y = 5,333.3333338

Get the same number of decimal places as for y:

10,000 × y = 5,333.33333383338

Note: 5,333.33333383338 = 5,333.3333338


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 = 5,333.33333383338 - 0.53333333338 ⇒

(10,000 - 1) × y = 5,333.33333383338 - 0.53333333338 ⇒

We now have a new equation:

9,999 × y = 5,332.8000005


Solve for y in the new equation.

9,999 × y = 5,332.8000005 ⇒

y = 5,332.8000005/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.53333333338

According to our calculations:

y = 5,332.8000005/9,999

⇒ 0.53333333338 = 5,332.8000005/9,999


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10,000,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

0.53333333338 = (5,332.8000005 × 10,000,000)/(9,999 × 10,000,000)

0.53333333338 = 53,328,000,005/99,990,000,000
