Q. Write the repeating decimal as a fraction.\newline.936936936.936936936
  1. Identify Repeating Pattern: Let's identify the repeating pattern in the decimal. The digits 936936 are repeating.
  2. Express as xx: Express the repeating decimal as xx: x=0.936936936x = 0.936936936\ldots
  3. Multiply by 10001000: To isolate the repeating pattern, multiply xx by 10001000 (since there are three digits in the repeating pattern): 1000x=936.9369361000x = 936.936936\ldots
  4. Subtract Equations: Now subtract the original equation x=0.936936936x = 0.936936936\ldots from the new equation 1000x=936.9369361000x = 936.936936\ldots:1000xx=936.9369360.9369369361000x - x = 936.936936\ldots - 0.936936936\ldots
  5. Solve for x: Perform the subtraction: 999x=936999x = 936
  6. Find GCD: Now solve for xx by dividing both sides of the equation by 999999: x=936999x = \frac{936}{999}
  7. Simplify Fraction: Simplify the fraction by finding the greatest common divisor (GCD) of 936936 and 999999. The GCD of 936936 and 999999 is 99.
  8. Perform Division: Divide both the numerator and the denominator by the GCD to simplify the fraction: x=936/9999/9x = \frac{936 / 9}{999 / 9}
  9. Check Simplification: Perform the division: x=104111x = \frac{104}{111}
  10. Check Simplification: Perform the division: x=104111x = \frac{104}{111} Check the fraction to ensure it is fully simplified. Since there are no common factors between 104104 and 111111 other than 11, the fraction is in its simplest form.
