Answer
As a decimal: $0.005$
As a fraction: $\frac{1}{200}$
Work Step by Step
To convert any percentage into a decimal divide by 100
(move the decimal two places to the left)
0.5% ÷ 100 = 0.005%
Finally remove "%" sign next to the 0.005% → 0.005
To convert any percentage into a fraction divide by 100, and remove "%" sign. (Write a fraction where the numerator is what the percentage was, and the denominator is 100)
$0.5$% $=\frac{0.5}{100}=\frac{1}{200}$
