College Physics Problem 1.17

State how many significant figures are proper in the results of the following calculations:
(a) (106.7)(98.2)/(46.210)(1.01)
(b) 
(c) 

SOLUTIONS:

(a) The answer is limited by 98.2 and 1.01. They are both 3 significant figures. So the result should be 3 significant figures.

(b) The answer is limited by 18.7. The answer should be 3 significant figures. So the result should be 3 significant figures.

(c) The answer is limited by 1.60 which is 3 significant figures. So the result should be 3 significant figures.
