Answer:
The decimal would be 0.008.
If you wanted a fraction in simplest form, it would be 1/125.
Explanation:
0.8% divided by 100 (move the decimal in the percent two places to the left) = 0.008
0.008 as a fraction is 8/1000, and then you divide both numbers by their GCF of 8, which will give you a fraction in simplest form of 1/125.
