When it says to put your answer according the worst number of significant figures as the question has, is lower or higher the worst number amount of sig fig.

E.g. Which one is worser? :
A) 0.1 Joules (1 sig fig)
B) 0.101 Joules (3 sig fig)

And does this count as 3 sig fig? :
0.100 Joules compared to 0.1 Joules

As a rule, if the question hasnâ€™t told you how many decimal places/sig figs for your answer, always stick with three. Iâ€™ve never encountered the phrase worst significant figures before so I hope Iâ€™m answering your question!
If the data given to you in the question is to eg 4 decimal places/ sig figs then your answer should be to 4 d.p/ sig figs too

0.100 j can be 3 sig figs, if your number was 0.0999, rounded up itâ€™s 0.100, might be worth revising significant figures!

The "worst" number would be 1 in that example. You'd generally give results at that level of asked for.
