Notice that zeroes before the first nonzero digit do not count as significant figures. The first nonzero digit counts as a significant figure. Then it's just a matter of keeping the next two. Note that even though the third digit is a zero, it still counts, as it is followed by a nonzero digit.
There are more rules for significant figures. I recommend reading the section of your textbook that includes this problem.
