How do you know which place value to round to?

Is there a difference between the numbers 51 and 51.0?

You look to the right when you round

A centimeter ruler is more precise because it is a smaller measurement

Yes, there is a difference between 51 and 51.0 because you now know that there is a 0 behind 51 and it was not rounded to become 51.

Units can be helpful because they can help you picture the world problem or convert any numbers like feet to inches properly.
