Answer 1

Significant Figures in Calculations:

In Order to Correct the Number of Significant Figures in a Calculation:

1.).  First, you would,  Add all the digits:  

(Example: 1405.2   +    9.77    +     4.32     =      1419.29)

2.).  Then, You would Round the final value to the Least Number of Significant Figures.  

(In Example, it would look like this:   1420).

Therefore, The least number of significant figures  in the Example, is 3.

(However, In the Example, the number 1420,)     The "0" isn't a significant figure.

Hope that helps!!!!                                  : )    

You didn't write the significant numbers in, So, I just gave you an Example, of how would actually solve Significant Figures Calculation!
