OpenStudy (nurali):
If 7 is your only certain number, then it can be written with 2 significant figures, 7.0 - where the .0 is uncertain and is one-tenth of the unit of measure. If the 7 itself is uncertain, then the true value could vary between 6.50 and 7.49. %error = (margin-of-error/measurement)*100%
