Convert 0.6--------- to a fraction, reduced to lowest terms.

1 answer

To convert the repeating decimal \(0.6\overline{0}\) to a fraction, we proceed as follows:

Let \(x = 0.6\overline{0}\).

  1. The repeating part consists of only one digit (the 0), so we multiply \(x\) by 10 to shift the decimal point one place to the right: \[ 10x = 6.\overline{0} \]

  2. Now, we write down the equation: \[ 10x = 6.0 + x \] The repeating portion remains \(x\).

  3. Subtract \(x\) from both sides: \[ 10x - x = 6 \] Simplifying gives: \[ 9x = 6 \]

  4. Now, solve for \(x\): \[ x = \frac{6}{9} \]

  5. We can simplify \(\frac{6}{9}\) by dividing both the numerator and the denominator by their greatest common divisor, which is 3: \[ x = \frac{6 \div 3}{9 \div 3} = \frac{2}{3} \]

Thus, the repeating decimal \(0.6\overline{0}\) as a fraction in its lowest terms is: \[ \boxed{\frac{2}{3}} \]
