Hey there! I'm happy to help!
First, we go to our ones place.
We look one digit to the right.
If this digit is 5 or greater, we add 1 to the ones place.
If it is 4 or less, we keep the 5 the same.
This digit is 9. So, we make the 5 a six. We also have to make every digit after the 5 into a 0, so our answer is 6.
Have a wonderful day! :D
