Significant Figures in Addition

Sum of the numbers \(436.32\text{ g}\), \(227.2\text{ g}\) and \(0.301\text{ g}\) is
663.821 g
663.8 g
6663.82 g
664 g

Solution:

In addition, the final result must be rounded off to the least number of decimal places of the terms. Here, \(227.2\text{ g}\) has one decimal place, so the sum \(663.821\text{ g}\) is rounded to \(663.8\text{ g}\).
