To convert the repeating decimal \(0.523523...\) into a fraction, we can follow these ordered steps:

  1. Let \( x = 0.523523...\).
  2. Multiply both sides by \( 1000 \) to shift the decimal places: \[ 1000x = 523.523523... \]
  3. Recognizing that \( 0.523523...\) is equal to \( x \): \[ 1000x = 523 + x \]
  4. Subtract \( x \) from both sides: \[ 999x = 523 \]
  5. Solve for \( x \) by dividing both sides by \( 999 \): \[ x = \frac{523}{999} \]

So, the ordered steps are:

  1. Let \( x = 0.523523...\).
  2. Multiply \( x \) by \( 1000 \): \( 1000x = 523.523523...\).
  3. Recognize that \( 523.523523... = 523 + x \).
  4. Subtract \( x \) from both sides: \( 999x = 523 \).
  5. Divide by \( 999 \): \( x = \frac{523}{999} \).

Therefore, \(0.523523... = \frac{523}{999}\).
