To express \(\frac{1}{2} \%\) as a decimal fraction, we need to go through a few steps:
1. Understand the percent format:
Percent means "per 100." Therefore, when we say \(\frac{1}{2} \%\), we are talking about \(\frac{1}{2}\) out of 100.
2. Convert the fraction to a decimal:
First, we convert the fraction \(\frac{1}{2}\) to a decimal by dividing 1 by 2, which gives us \(0.5\).
3. Adjust for percent to decimal conversion:
Since percent means per 100, we need to divide this decimal value by 100 to convert the percentage to its decimal form.
Hence, \(0.5 \div 100 = 0.005\).
So, [tex]\(\frac{1}{2} \%\)[/tex] expressed as a decimal fraction is [tex]\(0.005\)[/tex].
