Question

0.2748
Is my answer and the problem is sig figs... The question have two sig figs so would it be .27 or .28?

Answer 1

The rule I follow is to round the 0.2748 to 0.2750 and the 5 rule that says to round to the even number which rounds to 0.28 to two s.f. However, I don't know if the mathematicians agree with this. I see examples all over the net that would round this to 0.27. Perhaps a physics/math tutor will enlighten us. :-).

Answer 2

It's just .27
look only at the number after the number of sig fig you need when rounding.
