Question

How would I go and express these numbers with 3 significant figures in normal notation?

a)15.08
b)1444
c)83,909
d)0.524
e)0.0254

for d and e aren't they already with 3 significant figures and also in normal notation?

for a, b, and c I can't figure out what to do since It isn't explained how to get 3 significant figures in normal notation though I usually use scientific notation when questions like this come up.

Answer 1

Count three places. Round to the third. I use round to the even number for a number ending in 5.
a. 15.1
b. 1440
c. 83,900
d and e are ok as is.
