Full solution

Q. Write the repeating decimal as a fraction. \newline.88888888.88888888
  1. Identify Repeating Pattern: Identify the repeating pattern in the decimal.\newlineThe repeating decimal is 0.888888880.88888888\ldots, where the digit 88 repeats indefinitely.
  2. Assign Variable xx: Let xx equal the repeating decimal.\newlineLet x=0.88888888x = 0.88888888\ldots
  3. Multiply by 1010: Multiply xx by 1010 to shift the decimal point to the right by one place.\newline10x=8.8888888810x = 8.88888888\ldots
  4. Subtract and Eliminate Decimals: Subtract the original number xx from the result of step 33 to eliminate the repeating decimals.10xx=8.88888888...0.88888888...10x - x = 8.88888888... - 0.88888888...9x=89x = 8
  5. Solve for x: Solve for x by dividing both sides of the equation by 99.x=89x = \frac{8}{9}
  6. Write as Fraction: Write the repeating decimal as a fraction.\newline0.88888888=890.88888888\ldots = \frac{8}{9}
