Edexcel S1 A Level Maths

Can somebody just help me out? Urhm for edexcel S1 maths, for our answers for particular questions is it better to leave and answer as a fraction or a decimal?? And how many decimal places/significant figures should we leave our answer too?? Because the text book just does everything :smile: LOL

Personally, if the answer is a recurring decimal, I prefer to give it as a fraction. It really doesn't matter whichever you do, but if you choose to leave it as a decimal, I'd agree with the previous poster who said 3 s.f.. Make sure to write (3 s.f.) in brackets like that next to your answer though, to be on the safe side.

Best to give fraction mate. Otherwise do 3 s.f. It is recurring decimal such as 2/3.
