Ones Place: 4
Tens Place: 5
Hundreds place: 9
Too round 954, your going to find the hundreds place. Which would be 9. Once you've found the hundreds place, look at the number on it's left. If it's 5+ 9 would become 10, if it's under 5 that number would become 0 and so would every number too the right.
954 --> 1000
That being said, your answer is 1000.
I hope this helps! :)
