Q. Write the repeating decimal as a fraction.\newline.744744744.744744744
  1. Identify repeating pattern: Identify the repeating pattern in the decimal.\newlineThe repeating pattern is 744744.
  2. Assign variable x: Let xx equal the repeating decimal, so x=0.744744744x = 0.744744744\ldots
  3. Shift decimal point: Multiply xx by 10001000 to shift the decimal point three places to the right, since the repeating pattern has three digits. This gives us 1000x=744.7447441000x = 744.744744\ldots
  4. Subtract original xx: Subtract the original xx from 1000x1000x to get rid of the repeating decimals. This gives us 1000xx=744.7447440.7447447441000x - x = 744.744744\ldots - 0.744744744\ldots
  5. Perform subtraction: Perform the subtraction: 1000xx=999x1000x - x = 999x and 744.7447440.744744744=744744.744744\ldots - 0.744744744\ldots = 744.
  6. Set up equation: Now we have the equation 999x=744999x = 744.
  7. Divide by 999999: Divide both sides of the equation by 999999 to solve for xx. This gives us x=744999x = \frac{744}{999}.
  8. Find GCD: Simplify the fraction by finding the greatest common divisor (GCD) of 744744 and 999999. The GCD of 744744 and 999999 is 33.
  9. Simplify fraction: Divide both the numerator and the denominator by the GCD to simplify the fraction. This gives us x=744/3999/3x = \frac{744/3}{999/3}.
  10. Write final fraction: Perform the division: 744/3=248744/3 = 248 and 999/3=333999/3 = 333.
  11. Write final fraction: Perform the division: 744/3=248744/3 = 248 and 999/3=333999/3 = 333.Write the simplified fraction: x=248333x = \frac{248}{333}.
