"...to two significant figures." What's that??
Posted: Mon Oct 26, 2009 6:04 pm
Can anyone help?
DS was asked 2 Qs, both involving the phrase, "to two significant figures."
Q1. Approximate 623 to two significant figures.
Q2. Work out correct to two significant figures 0.72 x 2.7
I assumed the answer to Q1 was 620 and to Q2 was 1.9 but really don't know. Can any one help?
Many thanks!
