Full solution

Q. Write the repeating decimal as a fraction.\newline.994994994.994994994
  1. Denote Decimal as xx: Let's denote the repeating decimal 0.9949949940.994994994\ldots as xx.
    x=0.994994994x = 0.994994994\ldots
    To convert this repeating decimal into a fraction, we will first express xx in a way that isolates the repeating part.
    Multiply xx by 10001000 (since the repeating part has three digits) to shift the decimal point three places to the right.
    1000x=994.9949949941000x = 994.994994994\ldots
  2. Convert to Fraction: Now, subtract the original number xx from the result of the multiplication to eliminate the repeating decimals.\newline1000xx=994.994994994...0.994994994...1000x - x = 994.994994994... - 0.994994994...\newlineThis subtraction gives us:\newline999x=994999x = 994
  3. Solve for x: Now, we can solve for x by dividing both sides of the equation by 999999. \newlinex=994999x = \frac{994}{999}
  4. Simplify Fraction: The fraction 994999\frac{994}{999} can be simplified. Both the numerator and the denominator have a common factor of 11, which does not change the value when divided. Therefore, the fraction is already in its simplest form.\newlinex=994999x = \frac{994}{999}
