Thanks a ton. (link)

I don't know if you still need help on this, but I know the answer so I'll tell you-
basically when people talk about sig figs they're refering to the first three figures of a number; the significant ones. Numbgers after that are unsignificant.
For example,
98.763333333333
Draw an imaginary line after the third number (if you're looking for three sig figs. Otherwise adjust accordingly):
98.7/63333333333
now, just look at the number immediately behind your imaginary line. In this case it's a 6.
If the number after your imaginary line is a five or ABOVE, round the last number before your line UP. If it's BELOW five, round it DOWN.
So the 7 before the line would become an 8, since 6 is ABOVE 5.
So the answer is 98.8 (to 3 sig. figs.)
This method will work, no matter how many significant figures you are using.
