What is 0.2% as a decimal and a fraction

The correct answers are 0.002 and 1/500.

Explanation:
Percents are out of 100, which means 0.2%=0.2/100. To write this as a decimal, we divide 0.2 by 100; this is the same as moving the decimal 2 places to the left, so we get 0.002.

To write this as a fraction, we need to first move the decimal one to the right on the top and bottom (remember, what you do to the top of the fraction you do to the bottom); this gives us 2/1000, which simplifies to 1/500.
