Express the given percent as a decim \( \frac{1}{2} \% \)

To convert \( \frac{1}{2} \% \) into a decimal, first recognize that percent means per hundred. So, \( \frac{1}{2} \% \) can be expressed as \( \frac{1}{2} \div 100 \), which equals \( \frac{1}{2} \times \frac{1}{100} = \frac{1}{200} \). When you convert \( \frac{1}{200} \) into decimal form, it equals 0.005. When dealing with percentages, keep in mind that dividing by 100 shifts the decimal point two places to the left. Therefore, for simpler calculations, you can also directly take \( 0.5 \) (the decimal equivalent of \( \frac{1}{2} \)) and divide it by 100, which gives you the same result: \( 0.005 \).
