Full solution

Q. Write the repeating decimal as a fraction.\newline.119119119.119119119
  1. Identify Repeating Pattern: Let's identify the repeating pattern in the decimal. The digits 119\text{"}119\text{"} repeat indefinitely.
  2. Express as xx: Express the repeating decimal as xx: x=0.119119119x = 0.119119119\ldots
  3. Multiply by 10001000: To isolate the repeating pattern, multiply xx by 10001000 because there are three digits in the repeating pattern: 1000x=119.1191191191000x = 119.119119119\ldots
  4. Subtract Original xx: Now subtract the original xx from 1000x1000x to get rid of the decimal part: 1000xx=119.1191191190.1191191191000x - x = 119.119119119\ldots - 0.119119119\ldots
  5. Perform Subtraction: Perform the subtraction: 999x=119999x = 119
  6. Divide by 999999: Divide both sides by 999999 to solve for xx: x=119999x = \frac{119}{999}
  7. Simplify Fraction: Simplify the fraction by looking for a common divisor. The numbers 119119 and 999999 do not have any common factors other than 11, so the fraction is already in its simplest form.
