1. Given:
[tex]13.22+3.6[/tex]
To find the value and round to the correct number of significant figures:
In addition, we get,
[tex]13.22+3.6=16.82[/tex]
In order to figure out the correct number of significant figures to use for rounding the answer,
We notice that the number with the fewest decimal places in the question is 3.6, which has 1 decimal place.
So, our final answer should also have 1 decimal place.
Since 2 is less than 5.
Thus, the answer is 16.8
