Answer:
1/500
Explanation:
if you add a %, multiply the number by 100 (or move to the right 2 decimal places)
if you remove the %, divide the number by 100 (or move to the left 2 decimal places)
example .5 to a percent is .5(100) = 50%
to make this a fraction, first change the number to a decimal, then divide by 100, or multiply by 1/100.
.20 is the fractional number of two tenths or 2/10%.
(2/10)(1/100) = 2 / 1000 this can reduce to 1/500
