Answer

5299\frac{52}{99}

Step-by-step solution

4 steps
  1. Let xx be the recurring decimal.

    x=0.52‾x = 0.\overline{52}

    This means x=0.525252...x = 0.525252...

  2. Multiply the equation by 100 since there are two repeating digits.

    100x=52.525252...100x = 52.525252...
  3. Subtract the original equation (x=0.525252...x = 0.525252...) from the new equation (100x=52.525252...100x = 52.525252...).

    100x−x=52.525252...−0.525252...100x - x = 52.525252... - 0.525252... 99x=5299x = 52
  4. Solve for xx by dividing both sides by 99.

    x=5299x = \frac{52}{99}

    The fraction cannot be simplified further.

    The recurring decimal 0.52‾0.\overline{52} as a fraction is 5299\boxed{\frac{52}{99}}.
