What are the UB and LB of 9.82 and 2.46, correct to 3 significant figures?
Any ideas?
3. The rule is rounding.

9.82 correct to 3 s.f. means it has been rounded to 3 s.f. so you just find the highest number that rounds down and the lowest that rounds up.

For 9.82, that would be:

9.82499999999999 and so on
Which is just written as 9.825 (upper bound)

And 9.815.

That's all correct.
