How do you write an answer to 3 significant figures?

It is the first three figures of an answer. However if the answer begins with 0 you don't include that as a significant figure. For example if you have an answer of 0.2034768 to three significant figures it will be 0.203. The first significant figure is always either 1,2,3,4,5,6,7,8,9 and the next two numbers after that.

The first three numbers in a overall number. If it's say 15460, you would round to 15500 because it rounds up and trailing 0's don't count unless decimal

To write an answer to three significant figures, identify the significant digits starting from the first non-zero number, round if necessary, and format the answer correctly. For example, 0.004567 rounded to three significant figures is 0.00457. Keep in mind leading zeros are not counted as significant figures.
