Answer: 0.029
Explanation:
How you round this up is that you look at the 9 which is the last digit in the numbers that are there. Since it is five and above that makes the 6 turns into a 7. Then since the 6 is now into a 7 that means the 8 has to be rounded up to so that makes the 8 turn into a 9 that is why the answer is that way.
