In the number 3,400 the greatest place would be the 3. And in 800, the greatest place would be the 8. Basically it is the highest value in a number.
3000
What would be 159.45 if you round it to the greatest nonzero place
OK, I understand. Give me the number to be rounded, and I'll do that.
The greatest nonzero place is the number closest to the left (or the greatest number) that is not zero. So in this example, that would be the 8. So you would round the 8 up to a 9 (since 6 is greater than 4). So your answer would be 0.9

100
Whatever the greatest place is, look at the number immediately to the right of it. If that number is 4 or lower, zero it and everything to the right of it out. If that number is 5 or higher, increase the greatest place by one and zero everything to the right of it out.
