To convert \(0.5\overline{0}\) (which means 0.50000...) to a fraction, we'll follow these steps:
1. Let \(x = 0.5\overline{0}\).
2. To eliminate the repeating decimal, we multiply both sides of the equation by 10:
\[
10x = 5.0\overline{0}
\]
3. Now we can subtract the original \(x\) from this new equation:
\[
10x - x = 5.0\overline{0} - 0.5\overline{0}
\]
This simplifies to:
\[
9x = 4.5
\]
4. Now, divide both sides by 9 to solve for \(x\):
\[
x = \frac{4.5}{9}
\]
5. We can convert \(4.5\) to a fraction:
\[
4.5 = \frac{45}{10} = \frac{9}{2}
\]
So we have:
\[
x = \frac{9/2}{9} = \frac{9}{2 \times 9} = \frac{9}{18} = \frac{1}{2}
\]
Thus, the fraction representing \(0.5\overline{0}\) is:
\[
\frac{1}{2}
\]
