To find a number to two significant figures or any amount of significant figures you look at one plus the amount of asked figures, in this case the third significant figure, and if it is 5 or greater increase the asked amount of significant figures by one. If it is 4 or less make no changes to your number. Finally report the calculated number with the asked amount of significant figures.
