Hi

Can I please get some clarification on upper and lower bounds.

If the questions asks for the upper and lower bounds of 50 to thenearest centimetre, the answer would be49.5and50.5, right?

And if the question asks for the upper and lower bounds to the nearest 100, then the answer would be0and100.

So what I'm trying to ask is, if the question asks for the nearest 10cm, that there are 10 cm between the two bounds?

Thanks!
