Answer:
The correct answer is 0.021
Explanation:
It is asked that the student rounds to the thousandths, but he/she rounded to the hundredths. To fix his/her answer, they must go three places to the right of the decimal to the thousandths place and round the 0 up to 1 because the next place value is greater than or equal to 5. The correct answer is 0.021.
