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

  • 0.833333333338 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 = 0.833333333338


Set up the second equation.

  • Number of decimal places repeating: 12

  • Multiply both sides of the first equation by 1012 = 1,000,000,000,000


y = 0.833333333338

1,000,000,000,000 × y = 1,000,000,000,000 × 0.833333333338

1,000,000,000,000 × y = 833,333,333,338.833333333338


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.

1,000,000,000,000 × y - y = 833,333,333,338.833333333338 - 0.833333333338 ⇒

(1,000,000,000,000 - 1) × y = 833,333,333,338.833333333338 - 0.833333333338 ⇒

We now have a new equation:

999,999,999,999 × y = 833,333,333,338


Solve for y in the new equation.

999,999,999,999 × y = 833,333,333,338 ⇒

y = 833,333,333,338/999,999,999,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.833333333338

According to our calculations:

y = 833,333,333,338/999,999,999,999

⇒ 0.833333333338 = 833,333,333,338/999,999,999,999
